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.
