syscall: use clone3 syscall with CLONE_NEWTIME
CLONE_NEWTIME can only be used with the clone3 and unshare system calls,
see https://github.com/torvalds/linux/commit/769071ac9f20b6a447410c7eaa55d1a5233ef40c:
> All available clone flags have been used, so CLONE_NEWTIME uses the highest
> bit of CSIGNAL. It means that it can be used only with the unshare() and
> the clone3() system calls.
The clone3 syscall was added in Linux kernel version 5.3 and
CLONE_NEWTIME was added in version 5.6. However, it was non-functional
until version 6.3 (and stable versions with the corresponding fix [1]).
[1] https://lore.kernel.org/lkml/20230308105126.10107-1-tklauser@distanz.ch/
In case CLONE_NEWTIME is set in SysProcAttr.Cloneflags on an unsupported
kernel version, the fork/exec call will fail.
Fixes #49779
