Commas included in SPDX license expressions instead of 'AND'

[rnjudge]

When trying to validate an SPDX file from the ubuntu:latest image the resulting file does not validate due to error:

Analysis exception processing SPDX file: Invalid license expression.  Expecting more operands.
License expression: 'LGPL-2.1+, GPL-2.0+, LGPL-2.0+'

This is because the license expression should use AND instead of commas: LGPL-2.1+ AND GPL-2.0+ AND LGPL-2.0+
