7266e91f62 Move unique_fd fdsan tests into bionic. 
EXPECT_DEATH requires special handling to work with fdsan, because of
our fork detection. Instead of duplicating the EXPECT_FDSAN_DEATH macro
in the libbase tests as well, move the unique_fd fdsan tests here.

08b7a4008f fdsan: improve errors some more. 
Add handling for all 4 cases of failure of exchange_owner_tag. Also,
mask off and sign extend the type byte of the owner tag, and add a
test for that.

f6e5b58260 Introduce api to track fd ownership in libc. 
Add two functions to allow objects that own a file descriptor to
enforce that only they can close their file descriptor.

Use them in FILE* and DIR*.
