Downgrade sqlite3 and apsw to 3.6.22(-r1)

Even though the sqlite3 file included in p4a (`src/jni/sqlite3/sqlite3.c`) is a big cluster fuck (4 year old fork that has 2200+ lines different from the official sqlite v3.6.22 it claims to be and even has an unresolved merge conflict), it seems more reliable than the standard/updated sqlite version from https://github.com/lfdversluis/python-for-android/pull/3 and it seems to be the only way to get the apsw package working (only way to avoid IO errors).
