Add glob reference to source files

Like file or tree references, globs are restricted to the current
module; in fact, by the way we evaluate them, even to the top-level
directory of that module: a glob is a target having as artifacts and
runfiles those entries of the top-level directory of the specified
module that match the given pattern.
