Update apex dependency even for test and non-installable APEXes

The apex dependency map wasn't updated for test or non-installable
APEXes to work around the problem that a module being in such APEX
prevented the module from being installed in the system partition.

Since that problem is not happening any more, removing the unnecessary
work-around.
