t3401: add directory rename testcases for rebase and am 

Add a simple directory rename testcase, in conjunction with each of the
types of rebases:
  git-rebase--interactive
  git-rebase--am
  git-rebase--merge
and also use the same testcase for
  git am --3way

This demonstrates a difference in behavior between the different rebase
backends in regards to directory rename detection.
