We use `int` for `hooked_signals` but we can't just cast to whatever
`sigset_t` is because `sigset_t` is an opaque type. It's an unsigned int
on macOS. On macOS, `sigaddset` is implemented as a macro.

Just suppress -Wsign-conversion for `signals_init` for macOS given
there's no real nice way of fixing this.
