Upgrade: implement linkage repair
After upgrading existing kegs, we now search and upgrade their
dependents as well. If any are detected that have broken linkage, they
are reinstalled from source.

If there are any formulae in the dependents tree that are pinned, they
are only reinstalled if they're not outdated; in all cases, a suitable
message is printed detailing the kegs that will be acted upon.
