DecryptVerifyFilesController: fix verification of opaquely signed messages

- gpgme_op_decrypt_verify only works for opaquely signed messages
  when protocol==OpenPGP, so we now classify the input file in the
  DecryptVerifyOpaque case and only use DecryptVerifyTask if the
  input is potential ciphertext, otherwise we use VerifyOpaqueTask.

Partly fixes kolab/issue4156 (gpg4win).
What's missing is either bullet-proof classification
(also for binary content) or a way for the user to select decrypt
over verify-opaque in the UI.
