Implement system locale for Android

On Android, we would default to C locale always. We need a connection
to Java in order to get the locale, so this has to be done in the
platform plugin rather than the QtCore library. It's enough to
instantiate the QSystemLocale subclass, since this will automatically
register itself as the current system locale.
