sanitycheck: order results.csv and discards.csv deterministically

One of the first things needed when comparing builds of tests across
different environments/systems is to make sure the same (sub)tests were
selected and run in the first place. For that purpose sort the output of
--testcase-report and --discard-report as they were in random order.

Actually make the entire class TestInstance sortable by adding a
standard __lt__() method comparing unique instance names; it could be
useful again.
