Add command "loginctl enable-linger $USER" in install.sh

[yu-chenxi]

I install code-server on my ECS by executing install.sh.
Then execute following:

systemctl --user enable --now code-server
systemctl --user start code-server

But when I disconnect the ssh connection from my ECS, the code-server process will be killed immediately and the connection
between ECS and browser will break. Finally, I find this article systemd user instance to solve the problem.

This is solution.

loginctl enable-linger $USER

The issue is only happends when I run code-server as non-root user.
I think you shound add it.

It might be better to leave this as an option behind a y/n prompt than just do it by default. The enable-linger option has security implications if you're using ssh-agent+keychain or similar tools, and I don't think it should be interfered with silently.

Let's leave this open until a new release is cut.

I would recommend systemd stuff not be in the install script at all, since Amazon Linux 2 very deliberately does not include systemd user session support.
