Add UTF8String to the banned method list.

NSString's UTF8String can return null for some NSStrings, even if
|canBeConvertedToEncoding:NSUTF8StringEncoding| returns YES.
This has led to at least 2 crashes that were not encountered during
the development period.

marq@ do you think this is important to do now? 

It looks like the number of usage sites is now tiny. I'll clean them up and then close this.
