The session recording cockpit module is a bit behind the
cockpit-starter-kit master, so I just cherry-picked the 'Update bots
target for moved GitHub project' commit.
Afterwards, 'make bots' works fine but I see this error when
bots/image-customize is run from our makefile:
I compared it to the cockpit-starter-kit master Makefile, and it has
the same provided argument switches as far as I can tell.
