Andy Polyakov 74d9519a68 bio/b_print.c: recognize even 'j' format modifier.
'j' is specified as modifier for "greatest-width integer type", which in
practice means 64 bits on both 32- and 64-bit platforms. Since we rely
on __attribute__((__format__(__printf__,...))) to sanitize BIO_print
format, we can use it to denote [u]int64_t-s in platform-neutral manner.
