ci: exclude top-level scripts/prod files from hybrid system test

The hybrid_system_test path-trigger exclude glob was "scripts/prod/**/*", which
under fnmatch requires a subdirectory and so did NOT match top-level files like
scripts/prod/common_lib.py. As a result, prod-script-only changes still triggered
the (irrelevant, infra-heavy) hybrid system test instead of being skipped.
Use "scripts/prod/**" so all files under scripts/prod are excluded, matching intent.
