weston: add PACKAGECONFIG to build with systemd-login support

Automatically enable this support for distributions which have
systemd in DISTRO_FEATURES.

We add additional patches to weston, backported from Weston
git, to support the newer single libsystemd pkg-config file
and to make the enabling of systemd-login support explicit.
