Kees Cook 8b9a5269b4 randstruct: gcc-plugin: Fix attribute addition 
[ Upstream commit f39f18f3c3 ]

Based on changes in the 2021 public version of the randstruct
out-of-tree GCC plugin[1], more carefully update the attributes on
resulting decls, to avoid tripping checks in GCC 15's
comptypes_check_enum_int() when it has been configured with
"--enable-checking=misc":
