REGTESTS: h1/h2: Update script testing H1/H2 protocol upgrades

"http-messaging/protocol_upgrade.vtc" script was updated to test upgrades
for requests with a payload. It should fail when the request is sent to a H2
server. When sent to a H1 server, it should succeed, except if the server
replies before the end of the request.
