checkpatch: allow Closes tags with links

As a follow-up of a previous patch modifying the documentation to allow
using the "Closes:" tag, checkpatch.pl is updated accordingly.

checkpatch.pl now no longer complain when the "Closes:" tag is used by
itself:

  commit 76f381bb77a0 ("checkpatch: warn when unknown tags are used for links")

... or after the "Reported-by:" tag:

  commit d7f1d71e5ef6 ("checkpatch: warn when Reported-by: is not followed by Link:")
