Make pingout_duration configurable

In irctest I use faketime in some tests to make time pass 15 times faster for Sable so it does not have to actually wait a long time for some expiries to occur.
Along with Github CI's flakiness, this means that nodes sometimes exceed this timeout and kill each other, so I need it to be higher.
