util/lint: make clang-format non-fatal

The current clang-format configuration is completely broken. It forces
one to change the code style of patches before pushing them, only to
find out that checkpatch now complains about it. This means newcomers
get scared away, and developers only get angered and frustrated about
it, and end up working around clang-format's requirements anyway.

For now, make clang-format's complaints non-fatal, reducing them to text
noise. However, since clang-format is currently unusable, reverting it
out would be preferred.
