Add a new option 'x11-keymap' for configuring the X11 keyboard settings.
The value of the option is a dictionary with keys representing settings
which can be configured. Currently, only the 'layouts' setting can be
configured. Its value is a list of strings, representing the specific
layouts, which should be configured for the X11 keyboard.
Update the stage test case with the new option 'x11-keymap'.
