Massimiliano Culpo bd0fed7090 clang: add another regex for version detection (#12769) ...

This is similar to #10191. The Ubuntu package for clang 8.0.0 displays
a very unusual version string, and we need this new regex to detect it
as just 8.0.0

Unit test have been complemented by the output that was failing
detection.
