debugdirstate: add command to rebuildstate test to modify dirstate

Debugging the dirstate helps if you have options to add files for normal lookup
or drop them from the dirstate. This patch adds a convenience command to
test-rebuilddirstate.t to modify the dirstate. It will be used in the next patch
to write proper tests for debugrebuilddirstate --minimal
