SUMMARY
Valgrind does not support seccomp and suggested I open a bug about it. Log:
--2531113-- WARNING: unhandled amd64-linux syscall: 317
--2531113-- You may be able to write your own handler.
--2531113-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--2531113-- Nevertheless we consider this a bug. Please report
--2531113-- it at http://valgrind.org/support/bug_reports.html.

STEPS TO REPRODUCE
1. Compile a program and use the seccomp syscall. Nothing else is needed
2. use memcheck on the compiled binary
3. profit?
OBSERVED RESULT
A warning will be generated and the seccomp syscall will be ignore
EXPECTED RESULT
The seccomp call should work as intended
