security/gnupg: update to 2.4.9 latest oldstable release
Release notes are at
https://dev.gnupg.org/T8001
The Fedora update notice can be found on LWN at
https://lwn.net/Articles/1052769/
The Fedora notice is somewhat more informative because it explains
what CVEs are involved. This port update is a stopgap, so that
we have something to merge back to quarterly with minimal fuss.
