Bug#1102127: licenesecheck: Files with multiple OR licensing options

[Peter B]

The first two lines of the files are;

// Feel free to copy from this example to your own code
// SPDX-License-Identifier: 0BSD OR BSL-1.0 OR MIT-0

but licensecheck detects the license as just 0BSD,
missing the 'OR BSL-1.0 OR MIT-0' part.
