Support FreeBSD jails for testing

Ensure the test directory is read and writable to the test user.

If you request 127.0.0.1 in a FreeBSD jail without specific access
to 127.0.0.1 then the socket binds to the interface address to
maintain compatibility. This results in the log entries being
from the bound interface address. To prevent failure compare
with the bound IP when requesting 127.0.0.1 in combined test.
