Laurent Pinchart 2fa4ba01ff libcamera: Don't unnecessarily include event_notifier.h
The ipc_unixsocket.h and process.h internal headers don't need to
include event_notifier.h, the former because a forward declaration
suffices, and the latter because it doesn't use event notifiers. Remove
the unnecessary include, and include signal.h instead which is required
and was included indirectly through event_notifier.h.
