The previous commit implemented a C version of the t0021/rot13-filter.pl script. Let's use this new C helper to eliminate the PERL prereq from various tests, and also remove the superseded Perl script.

Ensure that parallel-checkout basically works on clone and checkout, spawning
|
|
the required number of workers and correctly populating both the index and the
|
|
working tree.
