of: add processing of EXPECT_NOT to of_unittest_expect 

scripts/dtc/of_unittest_expect processes EXPECT messages that
document expected kernel messages triggered by unittest.  Add
processing of EXPECT_NOT messages that document kernel messages
triggered by unittest that are not expected.

This is commit 2 of 2, implementing the processing of EXPECT_NOT
messages.
