Updated FindOpenEXR.cmake (1464)

There were a couple of issues with the FindOpenEXR.cmake.

1. The /usr/local paths were behind the /usr paths. I think it makes sense that if you compiled a new version of a library, the dependent code should point to that one.
2. Not having OPENEXR_HOME or ILMBASE_HOME set would cause the GENERIC_LIBRARY_PATHS to point to /lib (/lib64 in my case) before the paths that I expect them to be.
