Dmitry Vyukov a86f549703 runtime: add and use modtimer in netpoll 
Currently when netpoll deadline is incrementally prolonged,
we delete and re-add timer each time.
Add modtimer function that does both and use it when we need
to modify an existing netpoll timer to avoid unnecessary lock/unlock.

TCP4OneShotTimeout-6  17.2µs ± 0%  17.0µs ± 0%  -0.82%  (p=0.008 n=5+5)
SetReadDeadline-6      274ns ± 2%   261ns ± 0%  -4.89%  (p=0.008 n=5+5)

Update #25729
