Pull KUnit updates from Shuah Khan:
 "This consists of several fixes and enhancements. A few highlights:

   - Option --kconfig_add option allows easily tweaking kunitconfigs

   - make build subcommand can reconfigure if needed

   - doesn't error on tests without test plans

   - doesn't crash if no parameters are generated

   - defaults --jobs to # of cups

   - reports test parameter results as (K)TAP subtests"
