Qnx: Fix persisting of deploy steps

While the deploy steps re-used from RemoteLinux were created ok when
creating a new QnxDeployConfiguration, they did not survive a restart
(or rather a toMap/fromMap cycle, as the restoring insisted on having
a RemoteLinuxDeployConfiguration).

Since sharing DeployConfiguration*Factory*s is not yet possible, this
patch here creates additional DeployConfigurationFactories creating the
same steps, but insisting on a QnxDeployConfiguration parent.
