404bd9ff5d selftests/bpf: Add missing files required by test_bpftool.sh for installing 
test_bpftool.sh relies on bpftool and test_bpftool.py.

'make install' will install bpftool to INSTALL_PATH/bpf/bpftool, and
export it to PATH so that it can be used after installing.

7a3bdca20b selftests/bpf: Add default bpftool built by selftests to PATH 
For 'make run_tests':
selftests will build bpftool into tools/testing/selftests/bpf/tools/sbin/bpftool
by default.
