tests: move test APK with bad unicode filename to separate test

This filename has some messed up bytes related to bi-directional script
that is included (Left-to-Right and Right-to-Left).  GNU/Linux always
interprets filenames as pure byte sequences.  Windows and OSX store
filenames as Unicode strings.  So on OSX, the invalid filename gets
converted to a valid name.  That works fine, but the test fails because it
is compared to a file generated on Ubuntu, where it preserves the byte
sequence.

This includes an APK with a valid Unicode filename that includes
bi-directional script.
