libxtables: Revert change to struct xtables_pprot

While protocol values may exceed eight bits, the data structure is
indeed used only to store the static list of name/value pairs for faster
lookups. None of those has such a value and if one is added in future,
the compiler will complain about it.

So restore the old field type to retain binary compatibility.

Fixes: 556f704458cdb ("Use proto_to_name() from xshared in more places")
