The change to use angled includes for bpf_helper_defs.h breaks compilation
against libbpf when it is installed in the include path, since the file is
installed in the bpf/ subdirectory of $INCLUDE_PATH. Since we've now fixed
the selftest Makefile to not require this anymore, revert back to
double-quoted include so bpf_helpers.h works regardless of include path.

Fixes: 6910d7d3867a ("selftests/bpf: Ensure bpf_helper_defs.h are taken from selftests dir")
