ec: change usage of dummy

Google is working to change its source code to use more inclusive
language. To that end, replace the term "dummy" with inclusive
alternatives.

BUG=b:162781382
BRANCH=None
TEST=make -j buildall
     `grep -ir dummy *`
      The only results are in "private/nordic_keyboard/sdk8.0.0"
      which is not our code.
