harness: cleanup tests to not override is_finished() where possible

If is_finished() cannot be converted into get_finish_string(), i.e.
is_finished() is a condition that depends on multiple output lines make sure
we call super().is_finished(line) on every line so that we catch Assertion
errors etc. that are checked for in TestCommon.is_finished().

IRQ: Merge irqtest into driver e1000n driver

irqtest was duplicating the e1000 driver. This has been replaced
with an extra build command and the UNDER_TEST preprocess define.
Also, the binary name was changed to e1000n_irqtest as it better
reflects what its actually doing.

IRQ: Add priorioty to device_db. Additional device_db for kaluga

Drivers by kaluga now take an optional priority field in account.
When more than one driver matches the card, the one with the higher
priority gets started.
An additional device_db file can be specified to kaluga using the
add_device_db= parameter.
The irqtest now makes use of this to be started by kaluga.
