[PATCH] packagegroup: Add init-manager sanity check

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Currently, you can set VIRTUAL-RUNTIME_init_manager to an init system that
isn't in DISTRO_FEATURES. This leads to head scratching over unbootable images.

This adds a sanity check which ensures more valid systems are built.

(From OE-Core rev: 485413a33e981114722dfa096caf226f083f7aab)
