Note that this discards information about where path dependencies come from,

already fetched all dependencies.
Args:
deps_file: File containing deps information to be evaluated, in the
format given in the header of this file.
Returns:
A list of string paths starting under src that are required by the
given deps file, and all of its sub-dependencies. This amounts to
the keys of the 'deps' dictionary.
