Perform limited conflict checking with --force
Pacman currently bails when trying to extract a file over a directory
when using --force. Instead of ignoring all conflict, perform the
check and skip any file-file conflicts. Conflicts between directories
and files are still flagged and cause the transation to abort.
As a bonus, we now know about files changing packages when using
--force, so we can skip removing them fixing upgrade046.
