gpg-interface/gpgsm: fix for v2.3

Browse Source 
Checking if signing was successful will now accept '[GNUPG]:
SIG_CREATED' on the beginning of the first or any subsequent line. Not
just explictly the second one anymore.

Gpgsm v2.3 changed its output when listing keys from `fingerprint` to
`sha1/2 fpr`. This leads to the gpgsm tests silently not being executed
because of a failed prerequisite.
Switch to gpg's `--with-colons` output format when evaluating test
prerequisites to make parsing more robust. This also allows us to
combine the existing grep/cut/tr/echo pipe for writing the trustlist.txt
into a single awk expression.

Adjust error message checking in test for v2.3 specific output changes.
