Fix FTBFS after removal of gpg-error-config
Suggested Debian changelog:
* Add 0010-build-python-Don-t-use-gpg-error-config-gpgme-config.patch
and 0013-python-Fix-configure-generating-setup.py.patch from upstream
GIT master to fix FTBFS after removal of gpg-error-config.
Closes: #1022348
* Without gpg-error-config gpgme-config is not installed by the upstream
build system anymore. Adapt libgpgme-dev.install, drop related lintian
override and Debian specific manpage.
