cmGlobalUnixMakefileGenerator3: Fix memory leak warning
this->Makefiles.empty() is called twice, leading clang scan-build
to falsely believe that the delete statement was causing a memory
leak. Fix this by using a unique_ptr to hold the temporary
cmMakefile. This also has the benefit of making the code
exception-safe.
