local-ci-build: Add usage of NO_FORMAT_CODE
To test a local repo with changes not committed, set "NO_FORMAT_CODE=1"
before running `run-unit-test-docker.sh`, which is convenient for local
testing.

+## Run CI on local changed Repo
+
+If you have local changes in the repo, and you do not want to commit yet, it's
+possible to run local CI as well by setting `NO_FORMAT_CODE=1` before running
+the script.
+
+E.g.
+
+```shell
+WORKSPACE=$(pwd) UNIT_TEST_PKG=phosphor-hwmon NO_FORMAT_CODE=1 \
+./openbmc-build-scripts/run-unit-test-docker.sh
+```
+
+`NO_FORMAT_CODE=1` tells the script to skip the `format-code.sh` so that it
+will not format the code and thus your repo could contain un-committed changes.
