Install system server jar profiles into the APEX.

After this change, if profile-guided compilation is enabled for an APEX
system server jar, the profile will be installed next to the jar with
the ".prof" suffix, ("javalib/<name>.jar.prof"). This file will later be
used by odrefresh and dexpreopt from prebuilt APEX.
