Test helper functions mktmpfifo and chtmpdir were written
before t.Cleanup was available, which necessitated returning
of a cleanup function and the use of defer.
Let's use t.Cleanup (available since Go 1.14) and simplify the callers.
While at it,
- use t.Helper (added in Go 1.9);
- simplify some error messages (errors that come from os package
usually doesn't need to be wrapped).

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.
