Reactivate some tests by adding missing BUILD file
Reactivate some tests by adding missing BUILD file

The tests LfsDefinitionsTest, RangeTest, and DynamicSetTests weren't
covered by any BUILD file and hence weren't executed when running
all tests.

There don't seem to be any changes which deliberately created this
situation and hence deactivated those tests on purpose. We simply seem
to have 'lost' their coverage with a BUILD file, which is rectified by
this change.
