lib/tevent: remove spectacularly complicated manual subtraction

To be completely honest, I don't quite know whether to laugh or cry at
this one:

1 + (0xFFFFFFFF & ~(s.seen - s.count))
== 1 + (~(s.seen - s.count)) # s.seen, s.count are uint32_t
== s.count - s.seen # -A == ~A + 1

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
(cherry picked from commit 4279879c9847ca069527e11ca934b8906009cad8)
