dso__disassemble_filename() tries to get the filename for objdump (or
capstone) using build-id. But I found sometimes it didn't disassemble
some functions.
It turned out that those functions belong to a DSO which has no binary
type set. It seems it sets the binary type for some special files only
- like kernel (kallsyms or kcore) or BPF images. And there's a logic to
skip dso with DSO_BINARY_TYPE__NOT_FOUND.
As it's checked the build-id cache link, it should set the binary type
as DSO_BINARY_TYPE__BUILD_ID_CACHE.
