check-code: fix check for any/all function

The old check would only detect any/all at the beginning of a line.
The regexp was probably just modeled after the preceding regexp which
(correctly) finds the 'with' keyword at the beginning of a line.

We now complain about 'any(' and 'all(' anywhere in a line, unless it
is preceded by 'def'. This allows us to define our own compatibility
wrapper in util and use 'util.any(' in the code.
