sonarlint cli scan fails when scanning symlinks to directories

[sandrac...@googlemail.com]

When the source path being scanned contains a symbolic link to another directory then the scan is failing with error

ERROR: Fail to read file '/proj/new/src/cnf/symlink' with encoding 'UTF-8'
ERROR: Caused by: /proj/new/src/cnf/symlink (Is a directory)


The scan is failing with Sonarlint cli 2.0 and 2.1.  It works fine with Sonarlint cli 1.0
If source path contains symbolic links to files it works fine.
