criu: introduce clang-format to format source code

This is another attempt to introduce a tool to format CRIU's source
code. This time it is based on clang-format.

The .clang-format file is taken from the linux kernel git tree (5.13).

I removed all comments from lines which state that it requires at least
clang-format 4 or 5. For this resulting file at least clang-format 11
is required. See scripts/fetch-clang-format.sh for all the changes
done to the Linux kernel .clang-format file.
