udev: create symlinks for s390 PTP devices

Similarly to the udev rules handling KVM and Hyper-V PTP devices, create
symlinks for the s390-specific STCKE and Physical clocks (supported
since Linux 6.13) to have some stable names that can be specified in
default configurations of PTP/NTP applications.
