We see macOS CI job failures from time to time when the version of
p4 brew expects is slightly older than what is offered at Perforce's
download site.  Instead of failing to run the tests altogether, just
skip "git-p4" tests, like we do for tests that depends on any other
optional packages, when this happens.

This is essentially unchanged from the v3 posted by Carlo on April
23rd, with a few fix-ups that have been cooking on top squashed in.

The changes from the previous round (i.e. the "fix-ups" that have
been floating on top, which got squashed in) are:

 * The first step has a fix to a couple of wrong redirections that
   created a junk file whose name is "2", instead of sending the
   messages to the standard error.

 * The last step makes two places that we download Perforce packages
   to use https://cdist2.perforce.com/ (earlier one of the places
   used that, the other https://filehost.perforce.com/).

I am sending this out as a final "complain now, or this will go to
'next' soonish" warning.  The "What's cooking" report is getting
crowded with too many topics marked as "Expecting a reroll", and I'm
trying to do easier ones myself to see how much reduction we can
make.
