Add greg_t for arm64.

This was already present for the other architectures. I think we skipped
this because glibc seems to have an incorrect definition (int rather than
long), but the kernel has the sane definition (just not in a uapi header).

Clean up fpathconf(3)/pathconf(3).

fpathconf(3) and pathconf(3) can share code. There's no such
header file as <pathconf.h>. glibc/POSIX and BSD disagree about where
the _POSIX_* definitions should go.

Fix a couple more cases of missing CLOEXEC.

The debuggerd case can probably never happen, because you're crashing at this
point anyway. The system property one seems possible though.
