[ndctl PATCH v2 6/6] ndctl/test: add a new unit test for BTT error clearing

The new error injection command allows us to inject errors that persist through changing the mode of a BTT namespace to 'raw' and back. This allows us to test error clearing with a BTT by adding a selective error block to the raw namespace, enabling the BTT, and then clearing it via a write. Cc
