Henrik Boström f3a381adcd Use kHigh timer precision for 'delayed-ack' timers. 
In SCTP, sending ACKs at the right time is presumably important in order
not to cause unnecessary retransmissions.

This CL sets the ACK timers to use high timer precision. This unblocks
experimentally lowering the precision of the default, "low", timers in
WebRTC.

// All bots are green, but mac_chromium_compile is randomly timing out
// independently of this CL and has been doing so for several days...
NOTRY=True
