(PA-6549) Fix warning:undefining the allocator of T_DATA class

After puppetlabs/puppet#9349 was merged the
   warning: undefining the allocator of T_DATA class SWIG::TYPE_p_selabel_handle
error popped up again on RHEL-8 x86_64.

We ran into this previously and thought puppetlabs#620 fixed it
completely. This issue was completely fixed in swig 4.2.0+.

This commit patches selinuxswig_ruby_wrap.c with swig/swig@aa21014 and is
applied after the patch from puppetlabs#620 since the fix in
swig/swig@aa21014 came after.
