Update non-root operation

* Remove non-root instructions for docker systemd; behavior is different for docker
* Change listening port pairs to have container continue to listen on port 514 (`-p 2514:514`)

-# SC4S non-root operation
-
-To operate SC4S as a user other than root, follow the instructions above, with these modifications:
-
-## Prepare SC4S user
-
-Create a non-root user in which to run SC4S and prepare podman for non-root operation:
-
-```bash
-sudo useradd -m -d /home/sc4s -s /bin/bash sc4s
-sudo su - sc4s
-mkdir -p /home/sc4s/local
-mkdir -p /home/sc4s/archive
-mkdir -p /home/sc4s/tls
-podman system migrate
-```
-
-## Initial Setup
-
-NOTE:  Be sure to exectute all instructions below as the SC4S user created above with the exception of changes to the unit file,
-which requires sudo access.
-
-Make the following changes to the unit file(s) configured in the main section:
-
-* Add the name of the user created above immediately after the Service declaration, as shown in the snippet below:
-
-```
-[Service]
-User=sc4s
-```
-
-* Replace all references to `/opt/sc4s` in the "Environment" declarations with `/home/sc4s`.  Make sure _not_ to change the
-right-hand-side of the mount. For example:
-
-```
-Environment="SC4S_LOCAL_CONFIG_MOUNT=-v /home/sc4s/local:/opt/syslog-ng/etc/conf.d/local:z"
-```
-
-* Replace all references to standard UDP/TCP listening ports (typically 514) with arbirtrary high-numbered (> 1024) ports so
-that the container can listen without root privleges:
-
-```
-ExecStart=/usr/bin/docker run -p 2514:2514 -p 2514:2514/udp -p 6514:6514 
-```
-
-If not done in the "Prepare SC4S user" above, create the three local mount directories as instructed in the main instructions,
-replacing the head of the directory (`/opt/sc4s`) with the sc4s service user's home directory as shown below:
-```
-mkdir /home/sc4s/local
-mkdir /home/sc4s/archive
-mkdir /home/sc4s/tls
-```
-
-## Remaining Setup
-
-The remainder of the setup can be followed directly from the main setup instructions.
