Add tests for file dependency normalization behavior

There were no tests whatsoever for versioned file dependency
normalization, add some. This reveals that only filter unversioned
dependencies, but we do not filter multiple versions. I don't know
whether this is intended or not, but considering this is only done
for requires, recommends and suggests, we probably should.
