tests: only activate 'unset' alias if required This makes the test logs easier to read for most shells (which do not actually require that alias). This is especially important now that 'unset' is used in the new 'run_make()' function, and that function is likely going to be used more and more in the future. * t/ax/test-lib.sh (_am_unset, unset): Only define this function and alias if "unset VAR" returns a non-zero exit status when VAR is already unset.
