busybox: fix setting the kernel timezone

Browse source 
The settimeofday() syscall wrapper provided by musl filters out the timezone
argument, breaking the ability to set the kernel timezone through the function.

Adjust busybox patch to issue the syscall directly in order to circumvent the
problem.
