siteinfo.bbclass: Port over oe.dev logic for site files

In oe.dev we have a sets to pick out hostos/hostarch/etc site
files out of and include things like a common-linux site file.
This should also help out with adding multilib-specific site files
(ie x32).  In oe.dev we have an iterator but at Richard's request
we continue to return a list of files in siteinfo_get_files().
