Pull in febootstrap-supermin-helper (C version) from libguestfs.2.7

This commit also pulls in the automake C dependencies and gnulib.

febootstrap-supermin-helper is modified so that it has the
--kmods option (to read the whitelist, from the old shell script),
and so that it can read supermin appliances composed of multiple
parts from out of a directory.

Also: Updates to documentation.
