[mutter/wip/rstrode/rhel-8.0.0: 92/117] backends/native: update cursor on resume



commit 2a2697910ae2d979faad2b61b4334adb5ac28247

    backends/native: update cursor on resume
    
    As mentioned in a previous commit, the proprietary NVIDIA
    driver garbles memory on suspend. That behavior, means that
    the cursor gets corrupted on suspend.
    
    This commit forces the cursor to redraw itself when the
    logind session becomes active (on VT switch and resume).
