Add python to dependencies, fixes bpf build

Build error:

/usr/bin/env: ‘python3’: No such file or directory
make[3]: *** [Makefile:160: /build/src/linux-6.4/tools/bpf/resolve_btfids/libbpf/bpf_helper_defs.h] Error 127

At the line in the Makefile:

$(BPF_HELPER_DEFS): $(srctree)/tools/include/uapi/linux/bpf.h
        $(QUIET_GEN)$(srctree)/scripts/bpf_doc.py --header \
                --file $(srctree)/tools/include/uapi/linux/bpf.h > $(BPF_HELPER_DEFS)

In this case, python is required to execute bpf_doc.py.  Add python to
dependencies.
