bpf/tests: Allow different number of runs per test case
This patch allows a test cast to specify the number of runs to use. For
compatibility with existing test case definitions, the default value 0
is interpreted as MAX_TESTRUNS.
A reduced number of runs is useful for complex test programs where 1000
runs may take a very long time. Instead of reducing what is tested, one
can instead reduce the number of times the test is run.
