Patch to support pidfd_open()

SUMMARY

Linux pidfd_open() has been supported since 5.3 (https://man7.org/linux/man-pages/man2/pidfd_open.2.html) but is not supported on valgrind.

--2029068-- WARNING: unhandled amd64-linux syscall: 434
--2029068-- You may be able to write your own handler.
--2029068-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--2029068-- Nevertheless we consider this a bug.  Please report

Contribution is attached.
