t/pipe.t fails if the perl binary can't be found as 'perl'

Assumes that the perl binary can be found as 'perl'. This isn't always true; a simple example is a perl built without -Uversiononly, which will leave a binary named something like perl5.x.y.

Solution is trivial: like the following test, just use $^X instead of 'perl'

Hi Hugemeir, this should be fixed in this commit: https://github.com/ingydotnet/io-all-pm/commit/89bf1e776e3cc1cc668d0c8540f5fccbe1d00fcb - please check and let us know if it works for you.

@shlomif clearly that fixes it. I'm making a release now to include it.
