[bug#44880] [PATCH] gnu: ruby-rubocop: Update to 1.4.2.

[Tomás Ortín Fernández]

I'm finding it very difficult to package the updated rubocop from git, so here 
is a patch with rubocop 1.4.2 packaged from the gem. It was packaged from git 
because the gem doesn't include tests, but I can't figure out how to make the 
tests work. I have already asked for help at help-guix, and I'm sending this 
patch in the meanwhile because the current rubocop version is too outdated to 
be useful at all. As soon as I have the tests figured out, I will send a patch 
enabling the tests.

Tomás
