            Migrate to SPDX license

I changed the operator between BSD and GPL because the text in license say:
  You may select, at your option, one of the above-listed licenses.
And some part of zstd.c are licensed under MIT

This is part of https://fedoraproject.org/wiki/Changes/SPDX_Licenses_Phase_2
