lntest: extend the restore/restart methods to also accept optional SCBs

Browse Source 
In this commit, we modify the `RestoreNodeWithSeed` and `RestartNode`
methods to also accept an SCB. This will be useful in new integration
tests to properly exercise the various restore/restart scenarios using
static channel backups.
