lib: rearm pre-existing signal event registrations
process.on('somesignal', ...) semantics expect the process to catch the signal and invoke the associated handler. `setupSignalHandlers` perform the additional task of preparing the libuv signal handler and associate it with the event handler. It is possible that by the time this is setup there could be pre-existing registrations that pre-date this setup in the boot sequence. So rearm pre-existing signal event registrations to get upto speed.
