[PATCH] libelf: Mark shndx section dirty if gelf_update_symshndx updates it

[Mark Wielaard]

gelf_update_symshndx updates the symbol table data and (if given) the
extended section index data. But only the symbol table section was
marked as dirty. Also mark the extended section index section dirty if
the index data is updated.

        * libelf/gelf_update_symshndx.c (gelf_update_symshndx):
        Mark shndx section dirty.
