fuzz: use fuzzing confyaml for protodetect target

As is done for other targets,
so that all app-layer protocols are enabled,
even the ones disabled by default such as enip

And resets protocol detection every time we try
so that probing_parser_toserver_alproto_masks are fresh.

(cherry picked from commit 09c84d0c26)
