spdx30: Link license and build by alias

The license information and Build created by do_create_spdx are changed
to be referenced by their link alias instead of the actual SPDX ID. This
fixes a case where do_create_package_spdx would pull these from
mismatching sstate, and then the SPDX IDs would be unresolved when
assembling the final document
