[OE-core] [PATCH] shadow: use config 'attr' if distro has 'xattr'

[jobol at nonadev.net]

From: José Bollo <jose.bollo at iot.bzh>

When DISTRO_FEATURES has 'xattr' the shadow package
now automatically activates its config 'attr'.
The current implmentation is a copy of what is
made currently for libcap.
