CLEANUP: stktable: add some stktable flags polishing

Better late than never, commit 1f73d35 ("MINOR: stktable: implement
"recv-only" table option") implemented stktable flags and initial
definitions, but it lacks some comments plus the flag is stored as
16bits but the SKT_FL_ definition width allows for only 8bits so
it is a bit confusing, let's fix that
