bitbake: ConfHandler.py: allow require or include with multiple parameters

"inherit" already allows inheriting more than one class in a single
statement. The same also makes sense for "include" and "require",
because then one can generate a list of files to be included
dynamically also for the case that more than one file needs to be
included.
