python3-gpg 1.16.0-unknown version is incomparable, dependencies always fail

The python version of the gpgme version contains "unknown" and is therefore not PEP440 order compatible.

See this example:

  # pip3 freeze | grep gpg
  gpg===1.16.0-unknown

  # pip3 install pstore
  ...
  Successfully installed gpg-1.10.0
  Successfully installed pstore-2.0.0

  # pip3 freeze | grep gpg
  gpg==1.10.0

Key takeways from that example:

- pstore depends on gpg>=1.10

- 1.16 SHOULD be higher than 1.10

- pip installs 1.10 even though 1.16 exists

- the triple-= (gpg===1.16.0-unknown) means that the version exists, but cannot be version compared: https://peps.python.org/pep-0440/#arbitrary-equality

Suggested fix:

- replace the '-' from `gpgme-config --version` "1.16.0-unknown" with a '+'; that will compare as expected;

- fix so "-unknown" isn't appended.

Apparently, this is caused by insufficient fixes in 0001-avoid-identifying-as-beta.patch

I've attached a FIXED version, which should fix things.

Before:

  $ autoreconf -ivf

  $ grep Generated.*gpgme configure
  # Generated by GNU Autoconf 2.71 for gpgme 1.16.0-unknown.

After:

  $ quilt push
  Applying patch 0001-avoid-identifying-as-beta-FIXED.patch

  $ autoreconf -ivf

  $ grep Generated.*gpgme configure
  # Generated by GNU Autoconf 2.71 for gpgme 1.16.0.

Versions:

$ lsb_release -a 2>/dev/null| grep Codename
Codename: jammy

$ apt-cache policy python3-gpg | grep Installed
  Installed: 1.16.0-1.2ubuntu4
