selftests/bpf: More succinct Makefile output

Browse Source 
Similarly to bpftool/libbpf output, make selftests/bpf output succinct
per-item output line. Output is roughly as follows:

$ make
...
  CLANG-LLC [test_maps] pyperf600.o
  CLANG-LLC [test_maps] strobemeta.o
  CLANG-LLC [test_maps] pyperf100.o
  EXTRA-OBJ [test_progs] cgroup_helpers.o
  EXTRA-OBJ [test_progs] trace_helpers.o
     BINARY test_align
     BINARY test_verifier_log
   GEN-SKEL [test_progs] fexit_bpf2bpf.skel.h
   GEN-SKEL [test_progs] test_global_data.skel.h
   GEN-SKEL [test_progs] sendmsg6_prog.skel.h
...

To see the actual command invocation, verbose mode can be turned on with V=1
argument:

$ make V=1

... very verbose output ...
