base-files, metadata: support additional group membership
Some packages may require additional group membership for the system user added by that package. Allow defining additional groups as third member of the ':'-separated tuple, allowing to specify multiple ','-separated groups with optional GID. Example: USERID:=foouser=1000:foogroup=1000:addg1=1001,addg2=1002,addg3 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
