Normal builds will not contain support for some keystrokes but warn
about unknown keystroke actions:

Info: ignoring unknown keystroke action 'debug_tree'.
Info: ignoring unknown keystroke action 'regions_on_screen'.
Info: ignoring unknown keystroke action 'test_input'.
Info: ignoring unknown keystroke action 'deactivate_input_devices_grab'.

So we remove those from the default keystrokes config.
