lint: require license headers for .sh, .py, makefiles

Some file types generally did not use license headers before. Now .sh,
.py and makefile files will be required to include license headers. The
license header linter will enforce the requirement. All non-compliant
files are now updated with the correct headers.

Part of RE-658

Release note (general change): Change the license cockroach is
distributed under to the new CockroachDB Software License (CSL).
