One problem with seccomp was that ptrace could be used to change a syscall after seccomp filtering had completed. This was a well documented limitation, and it was recommended to block ptrace when defining a filter to avoid this problem. This can be quite a limitation for containers or other places where ptrace is desired even under seccomp filters. This adds tests for both SECCOMP_RET_TRACE and PTRACE_SYSCALL manipulations.
