1639b17c72 selftests/bpf: convert legacy BPF maps to BTF-defined ones
Convert selftests that were originally left out and new ones added
recently to consistently use BTF-defined maps.

ebb886078b selftests/bpf: remove bpf_util.h from BPF C progs
Though currently there is no problem including bpf_util.h in kernel
space BPF C programs, in next patch in this stack, I will reuse
libbpf_num_possible_cpus() in bpf_util.h thus include libbpf.h in it,
which will cause BPF C programs compile error. Therefore I will first
remove bpf_util.h from all test BPF programs.

This can also make it clear that bpf_util.h is a user-space utility
while bpf_helpers.h is a kernel space utility.

37739d1b4f selftests: bpf: Move bpf_printk to bpf_helpers.h
bpf_printk is a macro which is commonly used to print out debug messages
in BPF programs and it was copied in many selftests and samples. Since
all of them include bpf_helpers.h, this change moves the macro there.

bd4aed0ee7 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.
