virt-manager: Set SSH_ASKPASS_REQUIRE=force

Browse Source 
openssh 8.4p1 released in Sep 2020 finally added a feature
to force using SSH_ASKPASS instead of prompting on the commandline
for password, if a password would be required.

https://man.openbsd.org/ssh.1#SSH_ASKPASS_REQUIRE

Getting this behavior is basically what our whole fork dance is
about. Now we can do it with an environment variable

Let the user override it from the environment though, so there's
an escape hatch incase this causes unforseen problems
