Michal Niewrzal 1d62dc63f5 satellite/repair/repairer: fix NumHealthyInExcludedCountries calculation
Currently, we have issue were while counting unhealthy pieces we are
counting twice piece which is in excluded country and is outside segment
placement. This can cause unnecessary repair.

This change is also doing another step to move RepairExcludedCountryCodes
from overlay config into repair package.
