[OE-core] [PATCH 3/4] terminal.bbclass: import oe.terminal for oe.terminal.prioritized()

[Robert Yang]

Fixed:
INHERIT += "typecheck"
$ bitbake -p
ERROR: Failure expanding expression auto none ${@" ".join(o.name for o in oe.terminal.prioritized())}
which triggered exception AttributeError: 'module' object has no attribute 'terminal'
