linux_ppoll syscall patch for linuxulator v2

Thank you for taking a look in this.

You're right about the pointer to pa variable; I've dropped it and move the
declaration of pa early in the function.

Switched back to using ast() as in linux_pselect, dropped the 0s case, and
added handling the multiplication and addition potential overflows in a naive
way: if the result is smaller than the multiplicator or then the addend, then
timeout will get the INT_MAX value.
