Subject: Fix bug: Added syscalls for tasks example.
The tasks example stopped working on Linux (Ubuntu 22.04) due to the use of missing syscalls, which have been added in this fix. In addition, the definition files have been updated to include the newer clone3 system call (in the Linux kernel since 5.6) for new process and thread creation.
