[pushed] [gdb/contrib] Add missing copyright notice in check-copies.py

[pushed] [gdb/contrib] Add missing copyright notice in check-copies.py

[Tom de Vries]

I ran:
...
$ gdb/contrib/license-check-new-files.py -s gdb-18-branchpoint HEAD
...
and noticed that gdb/contrib/check-copies.py is missing a copyright notice.

Add this.
