[PATCH] t2024: mark test using "checkout -p" with PERL prerequisite

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Checkout with the -p switch uses the "add interactive" framework which
is written in Perl.

One test added in 8d7b558bae ("checkout & worktree: introduce
checkout.defaultRemote", 2018-06-05) didn't declare the PERL
prerequisite, breaking the test when built with NO_PERL.

Thanks, and sorry about my buggy code. I didn't consider the
interaction between -p and NO_PERL.

Your patch works, but I think just splitting the test up is better, so
we're not skipping things unrelated to "checkout -p" under NO_PERL.

I added your SOB since I stole significant parts of your commit
message.

Junio: We'd want one patch or the other before 2.19 so that release
doesn't break tests under NO_PERL.
