In an environment with unstable latency, such as upstream bufferbloat,
there are cases where a full netcheck could drop the prior preferred
DERP (likely home DERP) from future netcheck probe plans. This will then
likely result in a home DERP having a missing sample on the next
incremental netcheck, ultimately resulting in a home DERP move.

This change does not fix our overall response to highly unstable
latency, but it is an incremental improvement to prevent single spurious
samples during a full netcheck from alone triggering a flapping
condition, as now the prior changes to include historical latency will
still provide the desired resistance, and the home DERP should not move
unless latency is consistently worse over a 5 minute period.

Note that there is a nomenclature and semantics issue remaining in the
difference between a report preferred DERP and a home DERP. A report
preferred DERP is aspirational, it is what will be picked as a home DERP
if a home DERP connection needs to be established. A nodes home DERP may
be different than a recent preferred DERP, in which case a lot of
netcheck logic is fallible. In future enhancements much of the DERP move
logic should move to consider the home DERP, rather than recent report
preferred DERP.
