[PATCH v2 1/2] ci: make failure to find perforce more user friendly

["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.

Only one invocation of type is changed as that is what is only needed
for the expected future use case, and because `type` is recommended in
the CodingGuidelines, so changing that recommendation or a more complex
change has been specifically punted.
