Remove unnecessary loading of fileutils from path specs

These specs load artifice before Bundler boots because of their global
rubygems source. Artifice in turn loads `rack`, `rack-test`, and
`tmpdir` which in turn load `fileutils`.

Because of this, a missing `require` of `fileutils` in RubyGems would
not be caught by specs.

Loading artifice is not necessary for most of these specs, so remove the
global source to avoid it.
