The proper file that should be included is `sys/xattr.h` as that

`glibc` and not `attr/xattr.h` which ships with the `attr` utility.
We're most probably not the only ones because `attr/xattr.h` added a #warning to
their include resulting in the following compilation errors:
In file included from securityselinuxlabeltest.c:31:0:
/usr/include/attr/xattr.h:5:2: error: #warning "Please change your
<attr/xattr.h> includes to <sys/xattr.h>" [-Werror=cpp]
#warning "Please change your <attr/xattr.h> includes to
<sys/xattr.h>"
^~~~~~~
In file included from securityselinuxhelper.c:37:0:
/usr/include/attr/xattr.h:5:2: error: #warning "Please change your
<attr/xattr.h> includes to <sys/xattr.h>" [-Werror=cpp]
#warning "Please change your <attr/xattr.h> includes to

^~~~~~~
So looks like we were confused when first doing this. This header is provided
by the libattr-devel RPM so appears fine to use, but in fact only the
attr/libattr.h header is allowed. The attr/xattr.h header is in fact preventing
to be sys/xattr.h, as it contains this:
#ifndef _SYS_XATTR_H
#define _SYS_XATTR_H 1

Not pushing as build-breaker because we are still in freeze and I'd still like
someone with SELinux to check this patch. My VM with such system stopped
working just now =(
