Fix a couple of PM warnings.

- "Could not delete native binary" : This one is a bit of
  a WTF. git history tells us this code has been around for
  a very long time (the warning's new though). It's a no-op
  because codePath always contains the *current* codePath and
  trying to remove native libs from the current codePath will
  do nothing for bundled apps. This code sounds like it wants
  to delete dangling native binaries for system apps that were
  upgraded during an OTA. This sounds like a wrong place to do
  that, though.

- "Unrecognized code path" : This one's harmless and removed
  by moving this call closer to where it's used.
