app/prj.conf: stop forcing CONFIG_OUTPUT_DISASSEMBLY=y

This reverts 8f60180 ("app: enable OUTPUT_DISASSEMBLY for Zephyr
builds")

The disassembly is useful in some contexts but can't be parallelized and
takes an enormous amount of time. On my system OUTPUT_DISASSEMBLY
almost doubles the compilation time!

Quoting Zephyr commit cc5763344709:

> This on-by-default option takes the majority of "link" time. If people
> need the disassembly, they can turn it on.
