scripts: ci-build: add NO_ROOT_PASSWORD and EXPORT_TESTS

Two environment variables that can be used to control build output.

NO_ROOT_PASSWORD - If set to "true" will remove password on root
account. This is useful when running acceptance tests.

EXPORT_TEST - If set to "true", it will run an extra bitbake step
which shall export the OE QA tests and tools required to run them.
