Trace Redaction - Filter print ftrace events

Print events are used as many different ways. The most common usecase
is logging the begin and end events used by perfetto to display
slices. Some system processes use print events to log important events
(e.g. LMK).

Because print statments are freeform strings but have important
usecases redaction can't completely leave them as-is and can't
completely remove them. The happy medium is to drop all print
statements outside of the target package.
