[gearbox] provide common gbsyncd.service.j2 to start for platform specific gbsyncd docker (#9332)

Why I did it
Fix #9059. It provides common gbsyncd.service.j2 to start for platform specific gbsyncd docker, which must be named 'gbsyncd'.

How I did it
All of platform specific gbsyncd dockers use a common name 'gbsyncd'
Use a unique systemd service template gbsyncd.service.j2 for gbsyncd docker
