zephyr: zmake: Move CRITICAL output to ERROR
zephyr: zmake: Move CRITICAL output to ERROR

There really isn't an obvious distinction here between something that
is critical and something that is just an error. They are both errors
and stop the build, requiring user action. Drop this test and let
everything that doesn't otherwise match become an ERROR.

BUG=b:177096315
BRANCH=none
