(Maint) Don't mock with mocha

Without this patch applied the stdlib module has load-order issues with mocha
and rspec-puppet.  The root cause has yet to be determined, but we've narrowed
it down to this description:

  "If any rspec-puppet example groups run before parser function example groups
   and the parser function example groups use mock() then you'll get this error:"

You can exercise this explicitly with:

    rspec -fd spec/unit/puppet/{provider,type,parser}

This will ensure rspec runs all of the provider and type spec tests, which are
rspec-puppet ones, before the parser function specs are run.  I should also
note we empted out the test in the file_line provider to be nothing except an
empty describe block and this was still sufficient to trigger the load order
error described here.
