imfile: bugfixes in regard to large files (> 2GB)

- bugfix: a couple of problems that imfile had on some platforms, namely
  Ubuntu (not their fault, but occured there)
- bugfix: imfile utilizes 32 bit to track offset. Most importantly,
  this problem can not experienced on Fedora 64 bit OS (which has
  64 bit long's!)
