Subject: [PATCH 10/12] auditswig.i: avoid setter generation for
 audit_rule_data::buf

As it's a flexible array generated code was never safe to use.
With kernel's https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ed98ea2128b6fd83bce13716edf8f5fe6c47f574
change it's a build failure now:

audit> audit_wrap.c:5010:15: error: invalid use of flexible array member
    audit>  5010 |     arg1->buf = (char [])(char *)memcpy(malloc((size)*sizeof(char)), (const char *)(arg2), sizeof(char)*(size));
    audit>       |               ^

Let's avoid setter generation entirely.

Closes: https://github.com/linux-audit/audit-userspace/issues/252
