xattr: fix check for simultaneous glibc header inclusion
The guard was introduced in commit ea1a8217b06b ("xattr: guard against
simultaneous glibc header inclusion") but it is using #ifdef to check
for a define that is either set to 1 or 0. Fix it to use #if instead.
* Without this patch:
$ { echo "#include <sys/xattr.h>"; echo "#include <linux/xattr.h>"; } | gcc -E -Iinclude/uapi - >/dev/null
include/uapi/linux/xattr.h:19:0: warning: "XATTR_CREATE" redefined [enabled by default]
#define XATTR_CREATE 0x1 /* set value, fail if attr already exists */
^
/usr/include/x86_64-linux-gnu/sys/xattr.h:32:0: note: this is the location of the previous definition
#define XATTR_CREATE XATTR_CREATE
^
* With this patch:
$ { echo "#include <sys/xattr.h>"; echo "#include <linux/xattr.h>"; } | gcc -E -Iinclude/uapi - >/dev/null
