[PATCH] git-apply: modify prints to account for --3way changes

[Jerry Zhang <jerry@skydio.com>]

"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.

Add a --quiet flag to "git apply" so the user
can turn down the verbosity.
