prepare-ChangeLog: Fix some warning messages when using svn

<http://webkit.org/b/151914>

Reviewed by Daniel Bates.

* Scripts/prepare-ChangeLog:
(generateFunctionLists): Simplify logic so that we never call
normalizePath() with an undefined value.
(attributeCommand): Quote $subPath for the shell so that we
don't try to run "svn propget" on invalid paths.
