Add runit config

[tranzystorekk]

This is the closest to a running package for Void Linux I've been: https://github.com/tranzystorek-io/void-packages/tree/lemurs/srcpkgs/lemurs, including the runit files: https://github.com/tranzystorek-io/void-packages/tree/lemurs/srcpkgs/lemurs/files/lemurs

Some Void-Linux-specific notes so far:

• ttys 1-6 are reserved for console-only, so lemurs needs to be manually switched to tty7; especially if left on the default tty2, it breaks down into an ugly conflict with the already-running agetty instance
• the agetty -i flag is necessary, otherwise the issue text messes up the TUI display of lemurs
• running the xsetup.sh script seems flaky, I haven't been able to successfully launch a simple exec dbus-launch leftwm setup so far, while emptty works fine with its coded startx-like behavior

I guess for the first point, I should just make the tty configurable. This was already the plan. For the xsetup.sh script point, I feel like the emptty is a better approach than we are currently using. Might look into that.

Now that I come to think of it. The configuration file already has a TTY option which should be obeyed. This should solve the first problem hopefully.

I could add a PR for a --tty flag to be able to override the config file (would make it easier for the runit config)

I'm running Void Linux too and am searching for a small display manager.

Has there been any progress concerning this enhancement-issue?

Haven't tested lemurs on void for a hot minute, but I'd probably wait till the newest changes are released, like the desktop entry support
