Ensure the repo server has a valid log directory
Ensure the repo server has a valid log directory

This change is simply making sure that the repo server has a valid
log directory at "/var/log/nginx". In some cases, generally when
upgrading, this directory may not exists and because the package
is already installed the directory will not be recreated. This
change simply makes sure the log directory is created regardless.
