Add new modprobe-blacklist element.

This element can be used to provide a custom list
of modules via DIB_MODPROBE_BLACKLIST which
will be disabled via modprobe.d/blacklist.conf.

I'm using this to disable network adapters on the
Red Hat TripleO rack where the devices can't be
explicitly disabled via the BIOS.

In order to use set DIB_MODPROBE_BLACKLIST to the name of your
module. To disable multiple modules you can set DIB_MODPROBE_BLACKLIST
to a list of string separated by spaces.
Example:
