Fix setrlimit_test:setrlimit_memlock when the system has exceeded vm.max_wired.

[bdrewery]

Summary

This uses the same fix as r294894 did for the mlock test. The code from
that commit is moved into a common object file which PROGS supports
building first.

The mlock_test:mlock_err already exists and is a separate issue.

Sidenote: :mlock_err failing is something that I've known about for a while. It doesn't happen internal to Isilon, but it definitely happens on my workstations/VMs.
