Bug description:
  SRU Justification:

  [ Impact ]

  Users cannot save their X configuration files from nvidia-settings due
  to the called script not being marked executable

  [ Test Plan ]

  
  1. Run nvidia-settings
  2. Go to the X Server Display Configuration page
  3. Select a monitor in the layout and make any settings change to it using the controls below
  4. Click the "Save to X Configuration File" button
  5. On the "Save X Configuration" popup, click Save6
  6. The polkit auth prompt will pop up. Authenticated
  Expected / working:
  It works -- the xorg.conf file you specified is saved and you return to the nvidia-settings window without incident
  Actual / failing:
  It errors with "Unable to open X config file '{file you specified}' for writing.'

  [ Fix ]

  Set nvidia-polkit's mode to executable

  [ Where problems could occur ]

  Unlikely to cause a regression unless there is some caller that
  depends on nvidia-polkit *not* being executable

  [ Original bug report from rakslice ]

  I'm running version 0.18.3 of the package in 24.04 (noble).
  The package does not set nvidia-polkit executable, so the nvidia-settings app fails to save xorg.conf changes with a misleading error message.

  Clearly it is a python script, and simply setting it executable fixes the problem:
  sudo chmod +x /usr/share/screen-resolution-extra/nvidia-polkit
