tracing/user_events: Set event filter_type from type 

Users expect that events can be filtered by the kernel. User events
currently sets all event fields as FILTER_OTHER which limits to binary
filters only. When strings are being used, functionality is reduced.

Use filter_assign_type() to find the most appropriate filter
type for each field in user events to ensure full kernel capabilities.
