build/core: location of xattr.h

starting with libattr-devel-2.4.48-1 in Fedora 28 <attr/xattr.h> has
been removed from the package.

On Fedora, RHEL/CentOS, and SUSE, the glibc-headers package has provided
a near identical file, <sys/xattr.h>, in all the releases that we care
about.

On Debian, libc6-dev provides <sys/xattr.h> all the way back to 8/Jessie
and presumably all Ubuntu derivatives since then.

Note that on Debian the sys headers are installed in
/usr/include/$DEB_HOST_GNU_TYPE/sys/...
