Shared trees are supported by specifying the inner-tree as a list in the
mcombo file. This change enables that work.
Bug: None

The orchestrator path inside the test workspace (test/configs) is
build/make, which is different from the current path in multitree
(build/build/make). This was causing `python test_lunch.py` to fail
Rather than restructing the test workspace to build/build/make now (and
build/ later when the orchestrator is in its own project), create a
Context object which can be mocked.
Test: python test_lunch.py
