Fixing audit warnings

[mrjbq7]

Fixed a number of brew audit warnings.

• Switch to https urls
• Switch to ruby versions of mv, rm, touch, chmod
• Fix wiki.freedesktop.org urls

Before:

Error: 304 problems in 238 formulae

After:

Error: 38 problems in 36 formulae

Welp, this is going to set fire to the bots 😸. Homebrew doesn't usually accept such wide PRs, because when users do brew update they'll see a list of 300 formulae updated and most people panic in that situation. Maintainers here may welcome this PR in smaller chunks.

Yes, please do break this up and submit in in smaller increments (spread out over a longer period of time). Thanks!

Also, please avoid changing any gnome URLs, as I know others are working on these already.

@jacknagel couple questions:

1. How small, and over how many weeks would you like these changes to be spread? I would personally would rather rip the bandaid off quickly...

2. The gnome URLs are changed to https because brew audit produced warnings and were fixed. Why is this bad?

We have limited CI resources, and pull requests of this size block everything else from moving forward. I would say no more than 10 changed formula per PR, per day.

The gnome URLs are changed to https because brew audit produced warnings and were fixed. Why is this bad?

Because, as I said, others are already working on this and it will conflict with their work. Thanks!

Oh, I misunderstood re: gnome.

Okay, I'll do smaller patches!
