Allow running make_apk.py from any directory

per XWALK-2391, prepends the current location of make_apk.py when accessing files and directories assumed to be in the same directory as make_apk.py, including imports of other modules.
Thanks, I don’t plan to be an owner, actually.  In the contributing guidelines (https://crosswalk-project.org/#contribute/contributing-code) it said:
 “You should also add your name to the AUTHORS file the first time you make a patch.”
I didn’t find the AUTHORS file and thought OWNERS was used instead.  Please disregard it.

Please note that you're not supposed to add yourself to OWNERS like that -- the process<https://crosswalk-project.org/#contribute/reviewer_policy> is similar to Chromium's and involves an existing owner proposing your addition after a certain amount of significant contributions has been made.
