fix incorrect License field syntax

This fixes the following error generated by the `license-validate` tool:
```
$ license-validate -v 'GPL-2.0-only and LGPL-2.1-only'
No terminal matches 'a' in the current parser context, at line 1 col 14

GPL-2.0-only and LGPL-2.1-only
             ^
Expected one of:
        * AND
        * OR

Not a valid license string
```
