ci: lint all modules even if one module fails

The previous implementation stopped linting when it encountered its
first module that failed the linter.

Now, use a more idiomatic find|xargs pattern, which will run every
module and exit non-zero if any module fails to lint. This will speed up
the feedback cycle on CI in the event that multiple modules fail
linting.
