Commit 73cdf0c6ea9c ("perf symbols: Record text offset in dso
to calculate objdump address") started storing the offset of
the text section for all DSOs:

        if (elf_section_by_name(elf, &ehdr, &tshdr, ".text", NULL))
                dso->text_offset = tshdr.sh_addr - tshdr.sh_offset;

Unfortunately this breaks debuginfo files, because we need to calculate
the offset of the text section in the associated executable file. As a
result perf annotate returns junk for all debuginfo files.

Fix this by using runtime_ss->elf which should point at the executable
when parsing a debuginfo file.

I don't quite understand the debuginfo problem. I tested
this patch follow steps recorded in commit 99e87f7 and
see no problem.
