netfilter: x_tables: replace strlcat() with snprintf()

In preparation for removing the deprecated strlcat() API[1], replace the
strscpy()/strlcat() pairs in xt_proto_init() and xt_proto_fini() with
snprintf(), which builds each /proc file name in a single call.

Each name is "<prefix><suffix>", where <prefix> is the address-family
string xt_prefix[af] and <suffix> is one of the FORMAT_TABLES,
FORMAT_MATCHES or FORMAT_TARGETS literals. Prepend %s to the FORMAT
macros and switch to snprintf().
