In the long term, Hermit will also be usable as a monolithic OS. To prepare for this, an example of calling the fork system call is being integrated. In the case of a unikernel, the fork call will return an error (ENOSYS).
Add the system call `spawn_process`, which creates a new process from the executable file.
The segmentation offload driver feature can only be tested with sufficiently large packets. Add a new endpoint whose response size can be adjusted easily and that can be visually inspected for correctness. Co-authored-by: Martin Kröning <martin.kroening@eonerc.rwth-aachen.de>

Replace all `-22` placeholders in the user-side syscall layer with real `syscall!` invocations and extend `SyscallNo` with the matching numbers (18–53) for spawn/join, file metadata, condvars, task blocking and the socket API.
- extend the fork example to test the system call `exec`
