tests: latency_measure: Change reporting strings

Browse source 
Changes the summary lines used in the latency_measure benchmark
so that they follow a consistent pattern.

    OBJECT  action.<brief details about action>

This makes it easier to locate results belonging to a particular
object group. It also has the benefit to keep results colocated
should the output be sorted by an external tool.
