    libdw: Skip zero entries in aranges

    An address/length entry of two zeros is supposed to mark the end of a
    table. But in some cases a producer might leave zero entries in the
    table (for example when using gcc -ffunction-sections -gc-sections).

    Since we know the lenght of the table we can just skip such entries
    and continue to the end.

        * libdw/dwarf_getaranges.c (dwarf_getaranges): Calculate endp.
        When seeing two zero values, check we are at endp.
