e2image: attempt to use ftruncate64 to set i_size for raw images

If ftruncate64() exists, try to use it to set i_size.  This isn't
guaranteed to work, per SuSv3, but if it doesn't work, it's guaranteed
to return an error.  So for file systems and/or operating systems that
don't support extending i_size via ftruncate64(), fall back to writing
the trailing null.
