perf: emit progress output when unpacking & building

avar · gitster · commit b11ad029cb67 · 2017-05-21T08:25:38.000+09:00
Amend the t/perf/run output so that in addition to the "Running N
tests" heading currently being emitted, it also emits "Unpacking $rev"
and "Building $rev" when setting up the build/$rev directory &amp; when
building it, respectively.

This makes it easier to see what's going on and what revision is being
tested as the output scrolls by.
