Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.
