get_hex_build_id must not be based on soname, moreover playing with realname
on it, it is too fragile.  It should be based on addresses, you know that l_ld
is absolute address inside the library.  So find maps/smaps entry containing
l_ld, subtract its file offset from vaddr and you have the ELF header address.

Thinking about this, we have to do a real name on this as maps/smaps contain name as requested initially, not pathname as resolved.

While we can determine entry that corresponds to the given l_ld, the name sent to gdb needs to be realname as that is what gdb expects.
