utils/genrandconfig: check core-dependencies

When generating a random configuration, also check the host
dependencies for that configuration and error out if it fails.

This is mainly intended for the autobuilders, so they don't try to
build a configuration for which the necessary host packages are not
installed.

Instead of erroring out, we could also generate a different random
config. However:

- When called for the autobuilders, the autobuild-run script will
  anyway just attempt another build. The only difference is that a
  warning will be printed in this autobuild log now. This warning
  is in fact quite useful to hint that the autobuilder could benefit
  from intalling this additional host package.

- When called manually, the user may in fact want to install the
  missing host package and continue with the saved random config.

Fixes:
