Subject: ssh: T2635: migrate from a script base completion helper to a list

SSH mac, ciper and key exchange algorithms are not ynamically and only change
on distro upgrades. Thus it is easier to have them in a list and use a regex
based constraint. In the past users could have entered anything here!
