Subject: pactest: Do not remove symlink to directory if a to be installed
 package uses it

If a pacakge has a directory symlink (e.g. /lib -> usr/lib), do not
allow it to be removed if any other package is trying to install a
file into that path (e.g. /lib/foo).  This is because the local
database can become invalidated if the symlink is removed after the
package with file /lib/foo is installed (sync702.py).  If the symlink
is removed before the file is installed (sync701.py), the upgrade is
actually a success, but we can not guarantee the ordering so both
cases should fail.
