Looks like this was left over from #3.
When initializing fixed size structure fields from strings, the number
of bytes copied needs to be the minimum of the structure field and the
string byte count.
Fixes the following class of errors found when running a version of
class-dump build with ASan (Address Sanitizer):

CommonCrypto on OS X 10.11.5 started enforcing limits on the keysize which are too small, and so this couldn't dump Finder and Dock after that.
This fixes most of the remaining parse errors.
