upgrades: Fix premature adding of buster-backports sources
It is incorrect to check for backports availability, FreedomBox systems got
added buster-backports sources prematurely. This will lead to apt update
failures resulting in FreedomBox becoming unable to install new apps.

Fix this by removing old sources and adding new sources only after
performing (this time correct) backports URL check.

Closes: #1496.
