scons: Get rid of an unused fast model variable.

This held the location of the license file, assuming it actually was a
license file and not a license server URL. If this variable was unset
because the fast model configuration parameters hadn't been set, then
the "File" would resolve to the local directory, and SCons would get
upset that you'd called the same path a directory and a file.

We can avoid this problem by just getting rid of this variable, since
it isn't used anyway.
