[v3] tests: do more testing of block drivers

[PATCH v3 12/14] tests: fix check for sudo access in LUKS I/O test

Posted by Daniel P. Berrangé 3 weeks, 3 days ago

The test did not cope with the possibility that 'sudo' was not installed
at all, merely that it was not configured. This broke tests in any CI
env which lacks 'sudo'.
