merge: define conflict marker labels in filemerge()

Moves the conflict marker definition up to filemerge, so it gets applied to all
merge strategies, and so in a future patch we can manipulate the markers.

    Rather than attempting to merge files that were modified on both
    branches, it marks them as unresolved. The resolve command must be
    used to resolve these conflicts."""
