Add PPS core dependency for PTP module

- Added pps_core.ko module installation for PTP subsystem dependency
- Updated grep patterns in both scripts to include 'pps' modules
- Fixes 'Unknown symbol pps_register_source' errors for PTP functionality
- Ensures complete PTP/PPS dependency chain for e1000e and other drivers
