    libs/foreignmemory: Fix osdep_xenforeignmemory_map prototype
    
    Commit cf8c4d3d13b8 made some preparation to have one day
    variable-length-array argument, but didn't declare the array in the
    function prototype the same way as in the function definition. And now
    GCC 11 complains about it.
    
    Fixes: cf8c4d3d13b8 ("tools/libs/foreignmemory: pull array length argument 
to map forward")
