MINOR: stream/htx: add the HTX flags output in "show sess all"

Commit b9af88151 ("MINOR: stream/htx: Add info about the HTX structs in
"show sess all" command") accidently forgot the flags on the request
path, it was only on the response path.

It makes sense to backport this to 1.9 so that both outputs are the same.
