[PATCH v3 1/5] test: use bash specific test for feature tests

[David Bremner <david@tethera.net>]

It is desirable to have the tests consider these variables being
undefined as equivalent to the feature not being present, and in
particular for the tests not to generate errors.

We know the test suite is tied to bash anyway, so this is a simple
fix.
