Integrate migrate-run into bootmisc

The migrate-run service was hanging when parallel startup was enabled
because of its dependencies. This integrates the logic for this service
into bootmisc, which will avoid the issues with parallel startup.

I would like to thank Robin H. Johnson <robbat2@gentoo.org> for his
input on this patch
