test: loosen the test expectation

[compnerd]

The test expects the output location to be temp directory layout which
may not be the case. Loosen the test to enable moving the temporary
directory.

Replace this paragraph with a description of your changes and rationale. Provide links to external references/discussions if appropriate.

Resolves SR-NNNN.
