Add a dummy version number to the TurboJPEG dynamic library on Unix systems so Linux distro maintainers will not reject it out of hand.

 correct behavior of the colorspace extensions when merged upsampling is used.
 
+[5] The TurboJPEG dynamic library is now versioned.  It was not strictly
+necessary to do so, because TurboJPEG uses versioned symbols, and if a function
+changes in an ABI-incompatible way, that function is renamed and a legacy
+function is provided to maintain backward compatibility.  However, certain
+Linux distro maintainers will blindly reject any library that is not versioned,
+so this was an attempt to make them happy.
