Msf::Modules::Loader::Directory#each_module_reference_name created two
Pathname objects per module file and called relative_path_from to derive
the module reference name. With ~5,000 module files this produced
~170,000 calls to Pathname#chop_basename internally.
Since Rex::Find.find always yields absolute paths rooted at
full_entry_path, simple String#delete_prefix achieves the same result
without allocating Pathname objects.
