show the status output on failure (MR 2472)

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
