Static-checks: Take into account the new copyright string

Allow for both old and new style copyright lines to coexist
Also excluse psa/crypto_lms.h from the list of file to check
as we don't want to have PSA files checked as eventually they
will be owned by the Mbed TLS project, even if they are TFM
only extensions for now.
