The majority of Perl scripts we carry in Git have a `#!/usr/bin/perl`
shebang. This is not a portable location for the Perl interpreter and
may thus break on some systems that have the interpreter installed in a
different location. One such example is NixOS, where the only executable
installed in `/usr/bin` is env(1).
Convert the shebangs to resolve the location of the Perl interpreter via
env(1) to make these scripts more portable. While the location of env(1)
is not guaranteed by any standard either, in practice all distributions
including NixOS have it available at `/usr/bin/env`. We're also already
using this idiom in a small set of other scripts, and until now nobody
complained about them.
This makes the test suite pass on NixOS.
