p3400: stop using tac(1)

rscharfe · gitster · commit 100c2da2d3a3 · 2021-10-03T22:07:21.000-07:00
b3dfeeb (rebase: avoid computing unnecessary patch IDs, 2016-07-29) added a perf test that calls tac(1) from GNU core utilities. Support systems without it by reversing the generated list using sort -nr instead. sort(1) with options -n and -r is already used in other tests.
