[PATCH] weston-init: introduce WESTON_GROUP

["Richard Leitner" <richard.leitner@skidata.com>]

From: Richard Leitner <richard.leitner@skidata.com>

Currently the WESTON_USER variable is used as user and group name for
chown'ing XDG_RUNTIME_DIR. If WESTON_USER has no group with the same
name this fails.

Therefore add a new WESTON_GROUP variable which is set to WESTON_USER if
not specified to ensure backwards compatibility.
