gpgme: fix configure if 'import distutils' causes output on stderr

There are a number of reasons that importing a module could cause output on
stderr that isn't a fatal error (compatibilty problems with inputrc, or encoding
warnings) so backport a patch from autoconf-archive to only check the exit code
instead of asserting that stderr is empty.
