[PATCH RFC 0/7] tracing: Parse filter from event string

Make it possible to specify a trace event filter from the
kernel command line.

As a preparation also add a KUnit test for the event string parsing.

(Non-RFC series will get docs)

Patch 1 is a bugfix which is already useful.
Patch 2 is a cleanup which is already useful.
