Please unblock package golang-github-seccomp-libseccomp-golang
unblock golang-github-seccomp-libseccomp-golang/0.9.0-2
When I look the diff of unstable and testing of Go packages, I think
this could not be reverted. The changes are small and only contain bug
fix.

+ golang: Resolve bug with handling of multiple argument rules
+
+ In the upstream library, when added with a single API call,
+ multiple syscall argument rules should be matched with AND
+ logic - if all of them match, the rule matches.
+
+ At present, the Golang bindings apply OR logic to this case.
+ This commit resolves this and reverts to the behavior of the
+ main library.
