StatsD_Checker: Enable by default

It was previously disabled by default in order to avoid test breakage
with older versions of osmocom projects not supporting them. Since we
just did a new release, all -latest contian now master which should work
fine.

Don't remove the moduleparam yet in order to avoid breakage with some
cfg files in docker-playground.git still setting it to true.
