test-apt-cdrom: Fix for gnupg 2.1.15

gpg annoyingly changed its output and broke our test suite
again by adding two extra lines about key type and issuer.
Really annoying.

Those lines also have more than one space after the colon,
so let's use \s* there - and also change the other lines to
support variable length whitespace in case gpg decides to
break things there too.
