Fix some vendor-specific error reporting

Some decryption errors were being reported as
vendor-unique diagnostic codes that were not generally
actionable by an app.  Recently a new
MediaCodec.CryptoException code was added so these types
of failures can be reported as ERROR_UNSUPPORTED_OPERATION,
in which case the app can use an alternate DRM
configuration in a way that does not require
vendor-specific handling. This change remaps this class
of decrypt errors to the new error code.
