VS: Create a Fortran DLL's import library directory

The Intel Fortran plugin forgets to create the output directory into
which it will write a DLL's import library.  Utilize the fix added by
commit f4b3bdc6 (Create an exe's implib output dir for VS, 2009-06-15)
and generalized by commit 764ac980 (Generalize exe implib dir creation
for VS, 2009-06-16).  Create a pre-link rule to make the directory.
