Currently, some test scripts are experiencing minor errors related to
executing tests.
$ sudo ./test_cgrp2_sock.sh
./test_cgrp2_sock.sh: 22: test_cgrp2_sock: not found
This problem occurs because the path to the execution target is not
properly specified. Therefore, this commit solves this problem by
specifying a relative path to its executables. This commit also makes
a concise refactoring of hard-coded BPF program names.
