Subject: [PATCH] bpftool: Fix dependencies for static build

When building selftests/bpf with EXTRA_LDFLAGS=-static the follwoing
error happens:

make: *** [Makefile:327: /ws/linux/tools/testing/selftests/bpf/tools/sbin/bpftool] Error 2
make: *** Waiting for unfinished jobs....

This is caused by wrong order of dependencies in the Makefile. Fix it.
