Juan RP 5a1919e520 xbps_pkg_is_installed(): a pkg in "unpacked" state is now accepted as installed too.
The reason is that even if the pkg was not configured, it should still be accepted
as installed. If installing packages via XBPS_TARGET_ARCH, pkgs are never configured,
so this must be taken into account.

Will be cherry-picked to 0.37 meanwhile.
