Subject: gnu: ruby-listen: Enable running the tests.

* gnu/packages/ruby.scm (ruby-listen)[source]: Switch to the Git repository,
as this includes the tests.
[arguments]: Set #:test-target and tweak the Rakefile to avoid requiring
Rubocop unnecessarily.
[native-inputs]: Add bundler and ruby-rspec for running the test suite.
[inputs]: Add ruby-thor, as this is used for bin/listen.
[propagated-inputs]: Add ruby-dep, as this is listed as a runtime dependency
in the gemspec.
