    session: honor ignore-wayland flag
    
    commit 5b1e625417c274823c66a552f37d912986fc34d8 changed how the
    default session path was computed. It inadvertently dropped
    support for the ignore-wayland flag, breaking fall back to X in
    scenarios where wayland doesn't work.
    
    This commit fixes the code to again honor ignore-wayland.
