test: invoke all telemetry commands

Try and call all possible telemetry commands.
Each commands is tested with no argument, 0 (for command that accepts
a single integer like for a port identifier) and z (to catch commands
not properly validating input).
Fake cryptodev, dmadev, ethdev, eventdev and rawdev devices are created
using dummy drivers.

Output of the commands is not checked, the point of this test is mainly
to catch simple issues and leaks (when coupled with ASan in the CI).
