ci/ciimage: Lower nofile ulimit on containers that test D 

The D stdlib function std.process.spawnProcessPosix suffers from a bug
that causes any program that calls it to OOM if the nofile ulimit is
large.

This doesn't affect CI currently but trying to run or build the
containers locally will most likely crash when calling dub as docker
defaults to something like 1073741816 for both the hard limit and soft
limit. Lowering the soft limit is enough to make dub behave.
