[PATCH v4 1/4] ci: make failure to find perforce more user friendly

From: Carlo Marcelo Arenas Belón <carenas@gmail.com>

In preparation for a future change that will make perforce installation optional in macOS, make sure that the check for it is done without triggering scary looking errors and add a user friendly message instead.

All other existing uses of 'type <cmd>' in our shell scripts that check the availability of a command <cmd> send both standard output and error stream to /dev/null to squelch "<cmd> not found" diagnostic output, but this script left the standard error stream shown.

Redirect it just like everybody else to squelch this error message that we fully expect to see.
