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.
