cmd/internal/ld: delete Biobuf

Browse source 
Update #10652

This proposal deletes cmd/internal/ld.Biobuf and replaces all uses with
cmd/internal/obj.Biobuf. As cmd/internal/ld already imported cmd/internal/obj
there are no additional dependencies created.

Notes:

- ld.Boffset included more checks, so it was merged into obj.Boffset
- obj.Bflush was removed in 8d16253c90, so replaced all calls to
  ld.Bflush, with obj.Biobuf.Flush.
- Almost all of this change was prepared with sed.
