uxc: don't restart containers when mount shows up

procd triggers 'uxc boot' every time a new mount shows up which results
in containers to be restarted which had already been run and may have
ended reguarly, crashed or deliberately stopped.
As the intention of 'uxc boot' is to start containers which were still
waiting for volumes to become ready, really do only that.
