Don't wait on disabled dependencies.

When not using cvdalloc, the launcher will be disabled, but since
cvdalloc is a VmmDependency, crosvm will attempt to wait on it. This
fails immediately so there isn't an actual problem except for logspam,
but we shouldn't bother to wait on disabled dependencies in the
first place.
