    meson: Use LINGUAS file for help generation
    
    The linguas parameter is deprecated in gnome's yelp function for
    the future meson's versions.
    
    The patch uses the LINGUAS file instead of the linguas
    parameter. The polish translations has also been added as it was
    present in autotools but not in meson.
