tfa-next: tune copyright checker per project

Worth highlighting:

 - Python and shell scripts are kept in scope for RF-A since we might to
   develop tools with these scripting languages in the future.

 - All files and directories should be checked in the RF-A code base,
   with no exception. Source files we inherited from the TF-A project
   now all have a TF-A style copyright header as well as an RF-A style
   one since commits c7ba2fc3b ("refactor(rust): move assembly files to
   rust directory") and 24c893dba ("refactor(rust): move assembly
   headers under rust directory").
