Subject: [feat] search first for gpg1 binary

On debian stretch (and recent ubuntu) the gpg binary is version 2. If
installed gpg version 1 is found in /usr/bin/gpg1. Let's search for this
first.

I use the oportunity to clean up the code. I'm happy using symlinks, if
the user set them up let's use them.

- Resolves: #8901
