Fix fileconflict004
When one package wants to replace a directory by a file, we check that all
files in that directory were owned by that package.
Additionally pacman can be more verbose when the extraction of the symlink
(or file) fails. The patch to add.c looks more complex than it is, I just
moved and reindented code to handle cases 10 and 11 together.
