package_rpm.bbclass: Fix translate_smart_to_oe arch comparison
When the OE arch is of the format "foo_bar-foobar" the previous
comparison routine did not selectively translate the '-' causing
a failed comparison.
In order to work around this issue, we -always- compare the
RPM translated version of the package architectures.
