Currently, when we run test_progs with just executable file name, for example 'PATH=. test_progs-no_alu32', cd_flavor_subdir() will not check if test_progs is running as a flavored test runner and switch into corresponding sub-directory. This will cause test_progs-no_alu32 executed by the 'PATH=. test_progs-no_alu32' command to run in the wrong directory and load the wrong BPF objects.
