check-config: look for ui.configwith

We previously weren't looking for this config helper. And, surprise,
profiling.py references config options without docs.

If I tried hard enough, I could have combined the regexps using a
positive lookbehind assertion or something. But I didn't want to make
my brain explode.

At some point, we should probably do this linting at the tokenizer or
ast layer. I'm not willing to open that can of worms right now.
