We already had two copies of these constants, so time to factor them out

9700babc05 linker: disallow W + E PT_LOAD segments 
No mapped segment from the elf file can be writable and
executable at the same time. This commit adds a check
for malformed PT_LOAD segments in the elf-files.

c508de0e41 Use sysinfo(2) to implement more of <sys/sysinfo.h>. 
We already had implementations of some of the functions, and I didn't
bother rewriting them when we added sysinfo(2). Ross Anderson said in
https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/
that we should "simply disable access to all procfs files", which made
me curious how many places we use /proc in bionic. This is the one that's
obviously unnecessary. The others I'm not aware of alternative APIs for.

5ffed9b856 Move brillo closer to Android. 
Hiding our legacy cruft seemed like a good idea, but in practice it will only
mean worse interoperability.

Plus we got it wrong, as the recent `putw` example showed.
