Move manifest and certificates from orig Apk into the prepatched copy (if used)

Move manifest and certificates from orig Apk into the prepatched copy (if used)

This should help with the disappearing Apk, if this implements it correctly. I
still think I have seen the disappearances even with succesful patching though
which preserves the rom's certs/manifest by default. so this will not be a
general solution unless I am missing something. I am trying to avoid having
to try and sign all the apks, there are security ramifications of that and I
am not really willing to manage all the various key juggling it could entail.
