Only use the host's name in the test

The test uses `$(hostname)`, which can produce the FQDN; however, the
code only uses the host name portion of that. Modify the test to do the
same by defining a `hostname` function that calls the hostname(1)
binary then pipes it through sed(1).

Use command instead of hardcoding the path.

OS X uses `$HOSTNAME` instead of the result of hostname(1). In the test
suite, use `$HOSTNAME` first, falling back to hostname(1).
