Also update the documentation to indicate that this is a Wayland thing
and not dwl-specific.

This makes it ideal not only for initialization but also for execing into a
user-level service manager like s6 or `systemd --user`.
You'll have to explicitly set `XDG_RUNTIME_DIR` if your system doesn't do it for
you, e.g. `export XDG_RUNTIME_DIR=/tmp/xdg-runtime-$USER && mkdir -p
$XDG_RUNTIME_DIR`.
More/less verbose output can be requested with flags as well:
* `-q`: quiet (log level WLR_SILENT)
* `-v`: verbose (log level WLR_INFO)
* `-d`: debug (log level WLR_DEBUG)
Note: Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a
session manager such as `elogind` or `systemd-logind`. If your system doesn't
do this automatically, you will need to configure it prior to launching `dwl`,
e.g.:
export XDG_RUNTIME_DIR=/run/user/$(id -u)
mkdir -p $XDG_RUNTIME_DIR
