Fix multiarch package upgrade issue

When checking for negative dependencies in MarkInstall() ensure that
only dependencies that are relevant (i.e. getting installed) are
checked.
discard impossible candidates in MarkInstall

If a (Pre-)Depends can't be satisfied there is no point in keeping the
candidate as is as it is impossible to find a solution for it, so we can
just as well reset the candidate to the currently installed version.
We avoid trying to install this impossible candidate later on this way.
