net/netcheck: preserve live home DERP through packet loss
During a short period of packet loss, a TCP connection to the home DERP
may be maintained. If no other regions emerge as winners, such as when
all regions but one are avoided/disallowed as candidates, ensure that
the current home region, if still active, is not dropped as the
preferred region until it has failed two keepalives.
Relatedly apply avoid and no measure no home to ICMP and HTTP checks as
intended.
