lint: use *args and **kwargs everywhere

Many files used **dargs and **kwds.  Standardize on **kwargs.

The remaining handful used a func-specific variable name rather than
*args.  They kind of make sense, but they're the old balls out, so
let's standardize on *args to avoid this.

BUG=None
TEST=`./buildbot/run_tests` passes
TEST=linter no longer complains about these
