Specifying working directory for Runtime.exec() on linux has no effect

Passing the working directory as an argument to Runtime.exec seems to have no effect on linux...perforce still goes with whatever the VM's initial working directory was. You need to set -d to make it use the correct one.

In PerforceScmProvider.createP4Command():

command.createArgument().setValue("-d");
command.createArgument().setValue(workingDir.getAbsolutePath());
