Subject: [PATCH v2 bpf] kbuild: fix dependencies for DEBUG_INFO_BTF

Currently turning on DEBUG_INFO_SPLIT when DEBUG_INFO_BTF is also
enabled will produce invalid btf file, since gen_btf function in script doesn't handle *.dwo files.

Enabling DEBUG_INFO_REDUCED will also produce invalid btf file, and
using GCC_PLUGIN_RANDSTRUCT with BTF makes no sense.
