springboot Remove redundant exclusions

Hi,

I just noticed some dependency exclusions in spring-boot-dependencies that seem redundant. E.g. compare selenium-remote-driver:3.14.0 with selenium-remote-driver:3.141.0. On the latter, commons-logging is not a dependency anymore, while it is one in the former.

If I understood CheckBom correctly, it misses to check for non-wildcard excludes at the moment. This PR removes the redundant exclusions and handles non-wildcard ones inside CheckBom now.

Let me know what you think. Cheers, Christoph
