base.bbclass: Run oe_import before other INHERITs

Its possible for classes listed in INHERIT directives to use things like
the oe.utils functions. If that happens the user sees a traceback since
the modules don't become available until the ConfigParsed event.

This change to use immediate expansion means that the oe modules become available
much sooner and can be used in the core classes, including within base.bbclass.
