[PATCH v2 2/2] test/smime: fix signature verification test with newer gmime.

[michaeljgruber+grubix+git@gmail.com]

From: David Bremner <david@tethera.net>

The extra machinery to check for the actual output format is justified
by the possibility that distros may patch this newer output format
into older versions of gmime.

Here is what I meant with my comments: We have everything in place to
adjust the expected test output to the detected gmime behaviour. This
also takes into account dkg's remarks on the variable names.

[And yes, I have list bounces again, please forgive my mess and multiple
subscriptions to work around it.]
