check: silence ServerName warnings with MPM DSOs

When using shared MPMs, `httpd -V` will perform a full configuration
check, which emits warnings when there is no defined ServerName.
Unfortunately the test suite does a -V check for every test section,
spamming the output with noise.

Work around this by just uncommenting the example ServerName in the test
config.
