www-servers/nginx: add nginx-r2.service

This is the second revision of the systemd service file for NGINX.

This commit removes redundant Exec{Stop,Reload} lines that restate the
systemd defaults and changes the ExecStartPre directive from "nginx -t"
(testing the NGINX configuration that is done anyway by the main
process, bug 481456) to "mkdir -p /var/tmp/nginx", making sure the
required directory for the NGINX temp files is present. ExecStopPost has
also been removed, since sleeping for 100 ms serves no purpose.

The second revision also changes the Exec* directives to use the plain
file names, instead of the absolute ones, per systemd.service(5)
guidelines:
> It is thus safe to use just the executable name in case of executables
> located in any of the "standard" directories, and an absolute path
> must be used in other cases.
