Tobias Klauser 8ccfc68037 unix: add SysctlClockinfo on NetBSD
NetBSD uses sysctl with struct clockinfo to get clock rate information
from the kernel. Add type Clockinfo and the SysctlClockinfo function
to query this information.

This will be used in github.com/tklauser/go-sysconf to get _SC_CLK_TCK
on NetBSD.
