selftests: bpf: centre kernel bpf objects under new subdir "progs"
At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES.
Listing them manually sometimes causing patch conflict when people are
adding new testcases simultaneously.
It is better to centre all the related source files under a subdir
"progs", then auto-generate the object file list.
