On fedora rawhide seccomp_metadata for some
reason is not defined (while in kernel it introduced
together with PTRACE_SECCOMP_GET_METADATA). So
lets do a trick for a while -- define own alias.
Once system headers get settled down we might find
more suitable solution. Because it's a part of kernel
API we're on the safe side.
