    tools: Remove the use of K&R functions
    
    Clang-15 (as seen in the FreeBSD 14 tests) complains:
    
      xg_main.c:1248 error: a function declaration without a
      prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
      xg_init()
             ^
              void
    
    The error message is a bit confusing but appears to new as part of
    -Wdeprecated-non-prototype which is part of supporting C2x which formally
    removes K&R syntax.
    
    Either way, fix the identified function.
