Generate SPDX identifiers for License tag

[xsuchy]

Fedora is moving to SPDX license identifiers https://fedoraproject.org/wiki/Changes/SPDX_Licenses_Phase_1, and the list of licenses can be found in the package fedora-license-data, and it is already available in Fedora.
Can you please alter your script to generate SPDX identifiers in the resulting SPEC file?

I think these are the only two places which needs s/and/AND, because the Rubygems metadata already expects SPDX:

gem2rpm/templates/fedora-27-rawhide.spec.erb

Line 8 in 91b38c8

License: <%= spec.licenses.join(" and ") %>

gem2rpm/templates/fedora-27-rawhide-vagrant-plugin.spec.erb

Line 8 in 91b38c8

License: <%= spec.licenses.join(" and ") %>

Nevertheless, I am not sure if new templates should be created or just the old modified. It would be much easier if Fedora said that this applies e.g. F37 forward ...

I think SPDX now applies for all current Fedora releases. So this can more forward now?
