It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Fix up the all of the staging gasket files to have a proper SPDX identifier, based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.
