Always return pathname in dl_iterate_phdr's dlpi_name, as Linux does

Browse Source 
Linux LD_ITERATE_PHDR(3):
    The dlpi_name field is a null-terminated string giving the
    pathname from which the shared object was loaded.

That functionality is much more useful than returning just the short
name.
