Bump apm-perf in systemtest and tools

[carsonip]

Motivation/summary

apm-server tools is using an outdated version of apm-perf that does not
enable rewrite-timestamps and rewrite-ids in apmbench. Bump apm-perf
dependency to enable rewrite-timestamps and rewrite-ids. Not rewriting
ids is causing TBS to reuse trace ids and only output a subset of
events.

This will fail CI as new apm-perf moved loadgen into an internal package.
