In this case the new server name is expected to be logged, only in the Apache
version or the debug version of Nginx. The test is still valid, in the sense
that it is checking for the server response, expecting the new "Server:"
header.
The test is making usage of a custom script, which is not functional in
in Nginx due to timing issues. Disabling it for now until we came up
with a solution that works for every port/version.
It was trying to match "ModSecurity for Apache.* configured". This patch
makes it expect for "ModSecurity for nginx.* configured" while nginx
version is being used/tested.
