elf: fix handling of negative numbers in dl-printf

_dl_debug_vdprintf is a bare-bones printf implementation; currently
printing a signed integer (using "%d" format specifier) behaves
incorrectly when the number is negative, as it just prints the
corresponding unsigned integer, preceeded by a minus sign.

For example, _dl_printf("%d", -1) would print '-4294967295'.
