[PATCH v6 lkp-tests] tests: add hackbench-git test script
[Why] hackbench-git is an old version required by the customer. The hackbench-git usage: hackbench [-pipe] <num groups> [process|thread] [loops] So need to add new test script for hackbench-git.

This sentence is too long. You'd better divide it into some simple sentences. In fact, I didn't understand what does it mean~ Thanks, Yuanchao
