ui/cocoa.m: remove open dialog code

Removes the open dialog code that runs when no arguments are supplied with QEMU.
Not everyone needs a hard drive or cdrom to boot their target. A user might only
need to use their target's bios to do work. With that said, this patch removes
the unneeded open dialog code.
