[PATCH 26/33] Handle module alias properly

From: Hannes Reinecke <hare-l3A5Bk7waGM@public.gmane.org>

Some modules (like ext4) provide aliases by which the modules
can be accessed, too. But when using aliases directly dracut
fails to include the correct module. So translate the alias
into the correct module name before checking the module.
