net, os, internal/poll: test for use of sendfile

The net package's sendfile tests exercise various paths where
we expect sendfile to be used, but don't verify that sendfile
was in fact used.

Add a hook to internal/poll.SendFile to let us verify that
sendfile was called when expected. Update os package tests
(which use their own hook mechanism) to use this hook as well.

For #66988
