go net/http, x/net/http2: data race in multiple tests

#!watchflakes
post <- ((pkg == "net/http" || pkg == "golang.org/x/net/http2") && (`WARNING: DATA RACE` || `race detected during execution of test`)) ||
	(mode == "build" && log ~ `race detected during execution of test` && log ~ `FAIL	net/http`)

Combinding multiple watchflakes issues, e.g. #66499, #66489, #66484, #66479, #66476.
