[fix] "CodeChecker checkers" crash when infer used

If CodeChecker is installed by pip, then "CodeChecker checkers" command
crashes when fb-infer is installed. The reason is that description.json
file is not copied to the source distribution package.

In this commit the checker descriptions are replaced to the label file.
This eliminates the double administration of infer checkers and fixes
the crash.

Fixes #4502
