app_list: Elevate the verbosity level to 1.

This elevates it from 4 or 5 depending if it is a normal file or unit
test file to 1 for everything.

Used the following command line to lint the files:

$ for in $(g ls-files ui/app_list/ | grep -E '.*\.(cc|h)$' | grep -v
cocoa); do cpplint.py --verbose=1 $f; done
