t/: new helper for tests that pass with ort but fail with recursive

There are a number of tests that the "recursive" backend does not handle
correctly but which the redesign in "ort" will.  Add a new helper in
lib-merge.sh for selecting a different test expectation based on the
setting of GIT_TEST_MERGE_ALGORITHM, and use it in various testcases to
document which ones we expect to fail under recursive but pass under
ort.
