Switch from merge-recursive to merge-ort. Adjust the following
testcases due to the switch:
* t4151: This test left an untracked file in the way of the merge.
merge-recursive could only sometimes tell when untracked files were
in the way, and by the time it discovers others, it has already made
too many changes to back out of the merge. So, instead of writing the
results to e.g. 'file1' it would instead write them to
'file1~branch1'. This is confusing for users, because they might not
notice 'file1~branch1' and accidentally add and commit 'file1'.
In contrast, merge-ort correctly notices the file in the way before
making any changes and aborts. Since this test didn't care about the
file in the way, just remove it before calling git-am.
* t4255: Usage of merge-ort allows us to change two known failures into
successes.
* t6427: As noted a few commits ago, the choice of conflict label for
diff3 markers for the ancestor commit was previously handled by
merge-recursive.c rather than by callers. Since that has now changed,
`git am` needs to specify that label. Although the previous conflict
label ("constructed merge base") was already fairly somewhat slanted
towards `git am`, let's use wording more along the lines of the
related command-line flag from `git apply` and function involved to
tie it more closely to `git am`.
