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).

OpenBSD (like 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.

OpenBSD uses sysctl with struct uvmexp to get information from the
virtual memory system of the kernel. Add type Uvmexp and the
SysctlUvmexp function to query this information.
This will be used in github.com/tklauser/go-sysconf to get
_SC_AVPHYS_PAGES on OpenBSD.
