Subject: [PATCH] Move the Lima VM list out of the shared ssh module

* ssh.nix hardcoded nixden, the one host fact living in a module
  shared by all accounts and hosts. It now renders aliases from a
  my.limaVms option, so the host file that declares the VMs also
  declares their aliases, and accounts without VMs get an empty
  config.d/lima.
