oe-selftest: tinfoil: add tests for recently enabled datastore operations
A recent patch to bitbake fixes these datastore operations so that they
actually affect the server end, so we should test that they work.
(For full disclosure, some of these tests would probably pass without
those fixes, since the operation would be done on the client side
instead - but we are at least exercising the code paths.)
