Add test for freebsd issue #25809. This test also fails on my Windows 10 Version 1803. My hope is that adding new test will break one of our builders.

It also seems to be broken (probably in the same way) on dragonfly/amd64: https://build.golang.org/log/ee2bc4ad04e72093b84fbf7f2397f13b4d98e5ed |

On dragonfly, freebsd and solaris the sendfile syscall does not update the read position of the source fd. Update it after sendfile so successive calls start at the correct position.

I was trying to come up with a variation of TestSendfile to reproduce issue #25722 on our builder, and I end-up with
https://go-review.googlesource.com/c/go/+/117655/2
that fails on freebsd-amd64-11_1 builder with
--- FAIL: TestSendfile (0.00s)
sendfile_test.go:74: have="ProProPro", but want="Produced "
FAIL
I could be wrong about that test, but all other builders are OK with it. So I suspect that freebsd-amd64 sendfile implementation is broken.
Leaving for others to decide.
