[PATCH v2 0/1] Fix regression in t9902 with NO_PERL

The oneline notwithstanding, 13374987dd (completion: use _gitcompbuiltin for format-patch, 2018-11-03) changed also the way send-email options are completed, by asking the git send-email command itself what options it offers.

Necessarily, this must fail when built with NO_PERL because send-email itself is a Perl script. Which means that we need the PERL prerequisite for the send-email test case in t9902.

Changes since v1:

 * replaced the commit message by the cover letter, as it was deemed to be
   more informative.
