Absolut paths in sonar.python.pylint_config are prefixed with the path of the project

If I set the sonar.python.pylint_config to an absolute path (we share the same rc file with several projects), then it is prefixed with the projects path.

Steps to reproduce:
#. Start with a python sonar project
#. Set the sonar.python.pylint_config to an absolute path '/ABSOLUTE/PATH/pylint.rc'
#. Run mvn sonar:sonar -X

Expected result
The command line for pylint contains --rcfile=/ABSOLUTE/PATH/pylint.rc

Actual result
The command line for pylint contains --rcfile=/proj/pythonproject/ABSOLUTE/PATH/pylint.rc
