let insertModificationXcuFile accept "/" to indicate all nodes

insertModificationXcuFile takes a set of paths to include and a set of
paths to ignore from a given .xcu files

adapt this to allow an include path of "/" to match all contents of the
xcu.

insertModificationXcuFile is more useful than insertExtensionXcuFile for
the intended use case, because the latter inserts as an extension level
layer, and cannot override higher layers.
