selftests/bpf: Fix cd_flavor_subdir() of test_progs

Browse Source 
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.
