ntp: fix ntpd shutdown by using upstream patch After a series of amendments the seccomp.patch made ntpd work properly but only on 32-bit systems. This commit replaces that patch with the one submitted upstream by cleverca22 and that fixes the issue also on 64-bit systems. Close #38627, #45885

ntpd: Allow additional syscalls in seccomp filter. Fixes issue #21136. The problem is that the seccomp system call filter configured by ntpd did not include some system calls that were apparently needed. For example the program hanged in getpid just after the filter was installed: prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0) = 0 seccomp(SECCOMP_SET_MODE_STRICT, 1, NULL) = -1 EINVAL (Invalid argument) seccomp(SECCOMP_SET_MODE_FILTER, 0, {len=41, filter=0x5620d7f0bd90}) = 0 getpid() = ? I do not know exactly why this is a problem on NixOS only, perhaps we have getpid caching disabled. The fcntl and setsockopt system calls also had to be added.
