Andrew Dunham 9b5e29761c net/netcheck: ignore PreferredDERP changes that are small

If the absolute value of the difference between the current
PreferredDERP's latency and the best latency is <= 10ms, don't change
it and instead prefer the previous value.

This is in addition to the existing hysteresis that tries to remain
on the previous DERP region if the relative improvement is small, but
handles nodes that have low latency to >1 DERP region better.

Updates #8603
