Update Makefile to copy top-level demos files

Top-level files in the top-level "demos/" directory were not being
copied as they did not match the expression "demos/\*\*/\*". Change the
expression to "demos/\* demos/\*\*/\*" to cause all the files to be copied.

This solution is ugly and causes (harmless) "skipping directory"
warnings to be output by rsync.

It may be better to add the --recursive flag to rsync as a long-term
solution.
