backlight: run without a backlight device instead of panicking (0.4.3)
Release / package (x86_64, /var/local/cargo-target/iris-cargo-home, bare, /usr/bin/sccache, /var/local/rustup, /var/local/cargo-target) (push) Successful in 43s
Release / package (aarch64, , aarch64, , , ) (push) Successful in 2m20s

A config carrying a !backlight widget on a machine with nothing under
/sys/class/backlight (a laptop config on a desktop) hit
expect("did not find backlight device") in Backlight::new, which with
panic = "abort" killed wldash before a window appeared.

The device path is now Option<PathBuf>. A missing device, or a
configured `device` name that does not exist, prints one line on stderr
and leaves the widget in place so layout indices stay aligned: it
renders empty, skips sysfs reads and writes, and ignores clicks.
