[bpf-next,v3,1/2] selftests/bpf: Remove incorrect object path

From: Björn Töpel <bjorn@rivosinc.com>

The glob path, progs/*.bpf.o, is no longer a correct path. The BPF
object files reside in the top directory, or in the per-flavor
directory (e.g. cpuv4).

Remove the incorrect object path.

...and bpftool is missing.

I'll spin a v4. :-(
