[PATCH] mbuto: handle collections that don't require any modules

[Sevinj Aghayeva <sevinj.aghayeva@gmail.com>]

Currently we assume that given a test collection, there will always be some set
of kernel modules required for running the tests in the collection. This
assumption is false for some collection, such as seccomp, and this patch handles
such cases.
