Use "max-cache-size 2M;" by default in GitLab CI

In order to lower the amount of memory allocated at startup by named
instances used in the BIND system test suite, set the default value of
"max-cache-size" to 2 megabytes for GitLab CI BIND builds.  The purpose
of this change is to prevent named instances (or even entire virtual
machines) from getting killed by the operating system on the test host
due to excessive memory use.
