Alyssa Ross dc439e41db nixos/environment: move XDG_CONFIG_DIRS to sessionVariables
Otherwise, in non-interactive contexts (e.g. systemd units), this
entry (the default) won't be in the list.  Only the profile relative
ones would be, since they were already using session variables.  This
is clearly not the correct behavior.
