Fix OS_TEST_PATH in .testr.conf

As of commit 87f772c0bd59790aa43de59938d9c138963f9f4e the default
value for OS_TEST_PATH as set in .testr.conf is no longer valid.

In addition, because shell variables are evaluated in a
somewhat unintuitive order in situations like this, the default
wasn't being used properly anyway.  See link below for an
explanation why:

This commit fixes both problems.
