ExifInterface: Remove throwing exception

ExifInterface reads the first 5000 bytes of an image file to
determine what type of image it is, and throws an EOFException
if the file is smaller 5000 bytes. This CL removes the throwing
action.

Bug: 64133582
Test: Run ExifInterfaceTest.java with <5kb file
