package_deb.bbclass, cross-canadian.bbclass: DPKG_ARCH mapping function

Have DPKG_ARCH set by directly invoking a mapping function, rather
than using an anonymous Python function modify the variable under
the hood, so we can have proper handling of overrides.

Also bring in some additional mappings to Debian architecture names
that weren't being handled.
