[PATCH] combine --skip-missing to /check infrastructure

[Seewer Philippe <philippe.seewer-omB+W0Dpw2o@public.gmane.org>]

This patch introduces --skip-missing to skip modules failing /check,
allowing to use the check infrastructure not only for
dracutmodules="auto". 

Result: dracutmodules="auto" becomes obsolete, automatically setting
dracutmodules="all" and skipmissing="yes"

Patch is built on top of Harald Hoyers merge tree
(git://git.surfsite.org/pub/git/dracut.git)
