misc/sys/xattr.h: guard against linux uapi header inclusion
If the glibc xattr.h header is included after the uapi header,
compilation fails due to an enum re-using a #define from the
uapi header.  Protect against this by guarding the define and
enum inclusions against each other.

(A corresponding kernel patch has been sent here:
http://lkml.org/lkml/2014/3/7/331 )

(See https://lists.debian.org/debian-glibc/2014/03/msg00029.html
and https://sourceware.org/glibc/wiki/Synchronizing_Headers
for more information.)
