scripts: mandate that new files have SPDX-License-Identifier

Browse source 
Going forward we want all newly created source files to have an
SPDX-License-Identifier tag present.

Initially mandate this for C, Python, Perl, Shell source files,
as well as JSON (QAPI) and Makefiles, while encouraging users
to consider it for other file types.
