xabspath: use O_PATH for dirfd.
SELinux on Android is unhappy if you try to read "/":
avc: denied { read } for name="/" dev="dm-3" ino=2 scontext=u:r:hal_dumpstate_impl:s0 tcontext=u:object_r:rootfs:s0 tclass=dir permissive=0
That could happen via the open of ".." too, and potentially any other
directory might have similar restrictions, so move all of the open calls
to using O_PATH.
O_PATH seems more intention-revealing given what this function is doing anyway.
