[Skiboot] [PATCH] opal-prd: Add RestartSec to service script

We are seeing random failure of `opal-prd` during boot. Its failing during
boot mostly because prd module is not yet loaded.
Sample failure message:
Feb 21 19:03:09 grsp1 opal-prd: FW: Can't open PRD device /dev/opal-prd: No such file or directory
Feb 21 19:03:09 grsp1 opal-prd: FW: Error initialising PRD channel
We have `Restart` option in service script. But systemd will attempt to
restart as soon as it fails and stops after few attempts (by default it
retries for 5 times). This patch add `RestartSec` option to service script
RestartSec = Configures the time to sleep before restarting a service.
Note that I have pickedup 30sec as wait time. Before this change we hit
`opal-prd` failure within 50 reboots. With this fix 200 reboots went fine
without any failure.
