Breakpad Mac dumper: Change the dumper to be more C++-ish.

Browse source 
Instead of using bzero in main, use constructors to initialize the
Options structure.

Use C++ bool, not Objective-C BOOL.

Use a const NXArchInfo * to represent the architecture name, so that we can
use the NXGetLocalArchInfo, NXGetArchInfoFromName, etc. to handle things.

Delete the 'uuidStr' member; it is unused.

Leave Options::srcPath as an NSString, so that we can continue to use the
filesystem path abstraction methods provided by the Foundation framework.
