[PATCH 09/25] midx perf: add a perf test for multi-pack-index

Add a basic write and verify performance test for the multi-pack-index
command.

The reason for doing the "write" also in a "test_expect_success" is to
be friendly to skipping the "write" test as a perf test (which would
run N times) but still being guaranteed to have a midx to verify by
the time we get to the "verify" test.
