[release-branch.go1.9] internal/poll: be explicit when using runtime netpoller
internal/poll package assumes that only net sockets use runtime
netpoller on windows. We get memory corruption if other file
handles are passed into runtime poller. Make FD.Init receive
and use useNetpoller argument, so FD.Init caller is explicit
about using runtime netpoller.
Fixes #21172
