 We received a report that the app breaks when it is moved onto an external
 SD Card (or additional storage partition).

 {{{

 }}}

 It seems like tor-android-service is expecting a relative path for
 `libTor.so` within the app's local storage, but it is receiving an
 absolute path somewhere else.

 Moving Fennec onto an sdcard works, so we can see how geckoview loads
 libxul.
