Bug 1297515 - Always use the mozharness vendored copy of virtualenv, r=jlund This removes the option to pass in a custom virtualenv binary and gets mozharness to always use the copy in 'external_tools'. Because this is now deterministic, we don't need to do things like check what version of pip is being used. MozReview-Commit-ID: GWxkmaZVpsZ
