Become more restrictive around Runfiles#manifestExpander

Previously the contract was pretty liberal and could allow addition of
extra Artifacts. Create a more restrictive interface allowing the bare
minimum- adding empty files to the tree. This makes the contract of
Runfiles#getAllArtifacts() more sound, since arbitrary artifacts can't
be added, and it makes it easier to figure out what implementations of
manifest expansion exist out there.
