For some reason, dune's bootstrap process doesn't like
enabling CAML_INTERNALS. See the error in CI:
```
cd _boot && /Users/runner/work/dune/dune/_opam/bin/ocamlopt.opt -c -g -I +unix -I +threads spawn_stubs.c
vendor/spawn/src/spawn_stubs.c:481:20: error: implicit declaration of function 'caml_convert_signal_number' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
int signal = caml_convert_signal_number(Long_val(Field(v_signals_list, 0)));
^
1 error generated.

I'm not sure why, but it's easy enough to workaround it be declaring the
function that we need.
It's also a little cleaner this way as we only make the one private
function we need available rather than everything.
