livepatch: Update maintainers

Seth and Vojtech are no longer active maintainers of livepatch, so
remove them in favor of Jessica and Miroslav.

Also add Petr as a designated reviewer.

[[email protected]: Petr is the only one affected who hasn't provided his
 Ack by the time this patch has been applied, as he is offline curently;
 but I hereby assert that I've talked to him and he's OK with this change]
