trace/timerlat: Add migrate-disabled field to the timerlat header

Browse Source 
Since "54357f0c9149 tracing: Add migrate-disabled counter to tracing
output," the migrate disabled field is also printed in the !PREEMPR_RT
kernel config. While this information was added to the vast majority of
tracers, osnoise and timerlat were not updated (because they are new
tracers).

Fix timerlat header by adding the information about migrate disabled.
