gpgme: fix python setuptools invalid version issue

The python3-gpg's version is now '1.18.0-unknown'. Such version
has been treated as invalid for setuptools >=66.0.0. The error
message is as below:

  pkg_resources.extern.packaging.version.InvalidVersion: Invalid version: '1.18.0-unknown'
  (package: gpg)

Fix this issue by removing the '-unknown' suffix.
