Call update u-boot env once when a priority is changed

The recursive nature of calling the free priority function
would trigger setting the u-boot env multiple times.
Make a change so that the priorities are sorted and
updated once.

- Create a non-overriden priority setter function to be called
by the free priority function and by the function that creates
the dbus objects after a bmc reboot. There's no need to call
to free the priorities after reboot since the priorities are
preserved on the bmc, and if they're not they default to 0 or 255.
- When a dbus request is made to update the priority, update
the value, then call the free priority function, which will
sort the versions by priority and bump the priority of any
duplicate ones.

Resolves openbmc/openbmc#2535
