kbuild: Do not clean resolve_btfids if the output does not exist
Nathan reported issue with cleaning empty build directory:
$ make -s O=build distclean
../../scripts/Makefile.include:4: *** \
O=/ho...build/tools/bpf/resolve_btfids does not exist. Stop.
The problem that tools scripts require existing output
directory, otherwise it fails.
Adding check around the resolve_btfids clean target to
ensure the output directory is in place.
