pkg/csource: use 0 for missing syscall args
We don't specify trailing unused args for some syscalls
(e.g. ioctl that does not use its arg).
Executor always filled tailing unsed args with 0's
but pkg/csource didn't. Some such syscalls actually
check that the unsed arg is 0 and as the result failed with C repro.
We could statically check and eliminate all such cases,
but it turns out the warning fires in 1500+ cases:

So instead fill such args with 0's in pkg/csource too.
