For a single-liner like this, our stance has always been that t/
scripts can assume _some_ version of Perl interpreter available for
use, cf. t/README where it lists prerequisites and explains them:
- PERL
Git wasn't compiled with NO_PERL=YesPlease.
Even without the PERL prerequisite, tests can assume there is a
usable perl interpreter at $PERL_PATH, though it need not be
particularly modern.
So unless "receive-pack" that is being tested here requires Perl at
runtime, we do not want PERL prerequisite for this test.

Very good advice from a Perl expert; thanks.
