cmMakefile: Populate CMAKE_PARENT_LIST_FILE in callers. 

Because all external callers of this method pass a null first
parameter, this change has no effect for them.

This also makes it obvious that the CMAKE_PARENT_LIST_FILE is set to
the name of the file being read itself for CMakeLists.txt files,
which may not make any sense.
