Fix harmless printf abuse in symupload.
Fix harmless printf abuse in symupload.

symupload printed -[NSData length], an NSUInteger, using %lu. %lu is proper
to print a "long" as unsigned, but NSUInteger is a typedef for "unsigned int"
when building for 32-bit. This would not have caused any problems, because in
the 32-bit model, both int and long are 32 bits wide. In the 64-bit model,
long is 64 bits wide, but NSUInteger is defiend as "unsigned long", so there
wouldn't have even been a warning in that case.

This addresses the following warning:

symupload.m:137:30:{137:28-137:31}{137:46-137:59}: warning: conversion specifies type 'unsigned long' but the argument has type 'NSUInteger' (aka 'unsigned int') [-Wformat]
