perf annotate: Update DSO binary type when trying build-id

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.
