Don't let missing Treble property context files affect errno.
User code on a non-treble device was starting with errno == ENOENT rather
than 0 because of this treble support:
openat(AT_FDCWD, "/property_contexts", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
faccessat(AT_FDCWD, "/system/etc/selinux/plat_property_contexts", R_OK) = -1 ENOENT (No such file or directory)
This caused us to fail some toybox tests by reporting bogus errno values
where errno should have been left unset:
PASS: date -d @0
FAIL: date -d @0x123
