klp-build: Suppress excessive fuzz output by default
When a patch applies with fuzz, the detailed output from the patch tool
can be very noisy, especially for big patches.
Suppress the fuzz details by default, while keeping the "applied with
fuzz" warning. The noise can be restored with '--verbose'.
