apply: adjust messages to account for --3way changes

jerry-skydio · gitster · commit 526705fd3d14 · 2021-04-29T12:27:45.000+09:00
"git apply" specifically calls out when it is falling back to 3way
merge application.  Since the order changed to preferring 3way and
falling back to direct application, continue that behavior by
printing whenever 3way fails and git has to fall back.
