Do not require force-loopbreak on Protected packages

dpkg will be changed in 1.20.8 to not require --force-remove for
deconfiguration anymore, but we want to decouple our changes from the
dpkg ones, so let's always pass --force-remove-protected when installing
packages such that we can deconfigure protected packages.

Closes: #983014
