For future versions, we could add that to the reclaim command, turning
this into something like 'sudo port reclaim --work'. Does that sound
reasonable?

At first I thought about an 'unclean' pseudo-port, but that would still
require parsing all the ports, which is the time consuming part here.
Also, removing everything is more accurate, as there could be work
directories that do not match any port in the ports tree anymore.
