35bdfa040f use /system/bin/sh for all 
Since Treble, /vendor components has been using /vendor/bin/sh. But this
gets complicated with APEXes, /odm, apps, etc. We now switch back to
/system/bin/sh for all domains. In practice, this should be okay because
/system/bin/sh is almost stable.

140e4d35c0 grp_pwd_test: Hack around "trunk stable". 
The 2024Q builds don't have their own branches like QPR builds used to,
and there's no API bump until V proper, so the same CTS build needs to
cope with both last year's Android release _and_ the one that doesn't
have an API level yet. So poke holes in the uid test to support these
mismatches.

This runs the risk of allowing accidental misuse in U of the very uids
that will definitely be used in V, so check that _if_ the uids do exist,
they have the names we're expecting them to have. That should make
accidents easier to spot?

e65e1939a1 Reland^2 "[MTE] remap stacks with PROT_MTE when requested by dlopened library" 
Also enable stack MTE if main binary links in a library that needs it.

Otherwise the following is possible:

1. a binary doesn't require stack MTE, but links in libraries that use
   stg on the stack
2. that binary later dlopens a library that requires stack MTE, and our
   logic in dlopen remaps the stacks with MTE
3. the libraries from step 1 now have tagged pointers with missing tags
   in memory, so things go wrong

This reverts commit f53e91cc81.

Reason for revert: Fixed problem detected in b/324568991

Test: atest memtag_stack_dlopen_test with MTE enabled
Test: check crash is gone on fullmte build

6a45884851 Simplify our trivial initgroups(), and add a test. 
initgroups() is just a call to getgrouplist() followed by a call to
setgroups(). The tricky part is memory allocation. OpenBSD allocates an
NGROUPS_MAX-sized array of gid_t on the stack. FreeBSD allocates a
sysconf(_SC_NGROUPS_MAX)-sized array of gid_t on the heap. bionic had a
mix where it would try a 2-element stack array but fall back to a heap
allocation, which sounds reasonable if you want to avoid a 256KiB
(64Ki*4 bytes) allocation on either stack or heap. But that constant 2?
That's weird in two ways... It's really small (musl has an NGROUPS_MAX
of 32 unlike the Linux kernel's 64Ki, but 32 is still a lot larger than
2), but at the same time it's too big --- bionic's getgrouplist() always
returns a single element.

So although the FreeBSD "what the hell, let's just allocate 256KiB on
the heap" implementation would have been fine, there's really no point,
and anyone who's trying to understand initgroups() on Android really
needs to read getgroupslist() anyway, so let's just have the most
trivial implementation -- a single-element array -- and let's have it
right next to getgroupslist() in the same file as all the other <grp.h>
functions.

Also add a trivial smoke test. You mostly won't have permission to do
anything interesting with initgroups(), and it's basically unused save
for privilege dropping tcpdump and strace, but we may as well make an
effort. (I tested tcpdump before and after too.)
