Fix escapes in Fortran depend.make entries

Makefile dependencies must be escaped using cmLocalGenerator::Convert
with the cmLocalGenerator::MAKEFILE option.  This fixes Fortran module
dependencies with spaces in the path.  We test the fix by adding a space
to one of the module paths in the Fortran test.
