Add new cpp property "systemRunPaths".

The concrete use case is to prevent such paths from getting into the
list of rpaths, which can mess with the look-up of libraries in the case
where we linked against a different version than the one provided by the
system.

[ChangeLog] Introduced property cpp.systemRunPaths.
