Avoid signed integer overflow due to unary negation
The current X509_print_ex() tries too hard pretty printing negative
serialNumbers (which shouldn't occur in the first place). In particular,
negating LONG_MAX leads to signed overflow. Ditch the code dealing with
negative serialNumbers representable as long and fall back to the long
form printing. This simplifies the code and fixes
