Update/fix rpp_build_demos to support different "calling conventions"

This function was broken, because when invoked from Makefile, it built
only the first demo and not all demos specified as arguments. This is
now fixed.

Now, the function also accepts a single cell array with demo names. This
will be used by buildbot.
