Make license checks a bit less lenient.

This fixes license checks to apply to all java files under src/ as opposed to
only those in the org.elasticsearch package. It found some license headers that
had to be reformatted. I also added a missing license header to Nullability.java
however this has not be caught by the license checker since it ignores guice
files.

Relates to #13703
