merge tests: expect improved directory/file conflict handling in ort

merge-recursive.c is built on the idea of running unpack_trees() and then "doing minor touch-ups" to get the result. Unfortunately, unpack_trees() was run in an update-as-it-goes mode, leading merge-recursive.c to follow suit and end up with an immediate evaluation and fix-it-up-as-you-go design. Some things like directory/file conflicts are not well representable in the index data structure, and required special extra code to handle. But then when it was discovered that rename/delete conflicts could also be involved in directory/file conflicts, the special directory/file conflict handling code had to be copied to the rename/delete codepath. ...and then it had to be copied for modify/delete, and for rename/rename(1to2) conflicts, ...and yet it still missed some. Further, when it was discovered that there were also file/submodule conflicts and submodule/directory conflicts, we needed to copy the special submodule handling code to all the special cases throughout the codebase. And then it was discovered that our handling of directory/file conflicts was suboptimal because it would create untracked files to store the contents of the conflicting file, which would not be cleaned up if someone were to run a 'git merge --abort' or 'git rebase --abort'. It was also difficult or scary to try to add or remove the index entries corresponding to these files given the directory/file conflict in the index. But changing merge-recursive.c to handle these correctly was a royal pain because there were so many sites in the code with similar but not identical code for handling directory/file/submodule conflicts that would all need to be updated. I have worked hard to push all directory/file/submodule conflict handling in merge-ort through a single codepath, and avoid creating untracked files for storing tracked content (it does record things at alternate paths, but makes sure they have higher-order stages in the index). Since updating merge-recursive is too much work and we don't want to destabilize it, instead update the testsuite to have different expectations for relevant directory/file/submodule conflict tests.
