Android: Fix QDir tests

There's no way to install files automatically into the file
system on Android, so to test QDir on the file system, we have
to bundle the files in qrc and then copy them into the file system
on startup. This adds some complexity, but at least it will detect
regressions.

We also need to make sure the current directory is the same as
the data path, since the test assumes this, and /usr/ does not
exist on Android, so we have to use a different path to find the
root path.
