show the status output on failure

There is a lot of context and state management needed when using pmbootstrap, sometimes it can be a lot to keep in your head. Let's print the output of "pmbootstrap status" when stuff goes wrong, this might help remind people if e.g. their pmaports checkout is on the wrong branch, or they're building for the wrong device.

Additionally, don't print the "run pmbootstrap log for details" message if pmbootstrap was called with --details-to-stdout
