Add support for APEX packages in system partition to apexd.
In addition to scanning and loading APEX packages from /data/apex,
also do so from /system/apex, in that order -- so that packages in the
former location can override packages from the latter location.
Test: Build product containing ART minimal APEX module (see
https://android-review.googlesource.com/774928) in
/system/apex, flash and boot device with it, and check that
the ART APEX module is mounted correctly.
