Refactor tss request requirements to work with iPhone 3G and iOS 4

This gets rid of the device model checking code and allows
devices like the iPhone 3G to get shsh blobs as required by iOS 4.
The requirement if the components need to be signed is determined
by which kind of manifest filename is within the IPSW.
