metrics_SUITE: Increase the timer after force_channel_stats()

The change introduced in rabbitmq/rabbitmq-common#154 to restore
compatibility with Erlang R16B03 and 17.x makes the cost of the first
call(s) to rabbit_core_metrics more expensive.

Increasing this timer allows the testsuite to succeed again.
