This change adds kmod querying support for FreeBSD, allowing tests to
require specific kmods using the require.kmods metadata in testcases,
or the atf_require_kmod function in atf-c(3), atf-c++(3), and
atf-sh(1).

This functionality has been stubbed out and is expected to fail/not be
available on all other OSes, e.g., Linux, macOS, etc.

A corresponding paired change is required in order to make this
functionality work with kyua. That change is coming soon.

This is a forward port of kmod support from [https://github.com/freebsd/atf/commit/83a1ee57][1]. The
original implementation was by Dag-Erling Smørgrav.

This change improves direct code coverage in this area; other testcases
may have previously exercised these code paths but this improves code
coverage by adding tests to explicitly exercise these APIs.
