tools/nolibc/poll: use kernel types for system call invocations

The system calls expect 'struct __kernel_old_timespec'.
While currently 'struct __kernel_old_timespec' and 'struct timespec' are
compatible, this is confusing. Especially as future patches will change
the definition of 'struct timespec'.

Use the correct kernel type instead.
