[BUG] clight spams journal with Ambient brightness

[Tinter]

NOTE: Please try to upgrade Clight if not running on latest release, before reporting a bug!

Clight version the issue has been seen with:

4.11-706250c

Used distribution:

Arch Linux

Describe the bug
clight spams journald with lines looking like "Jun 03 20:13:02 nyaarch clight[2603]: Ambient brightness: 0.644, Screen brightness: 0.686 -> Screen backlight: 0.660."
Of course varying in actual numerical values.

Expected behavior
These lines don't really do much, maybe they're useful for debugging, but they're just noise making it harder to see what is going on in a running system.

To Reproduce
I do not think I'm doing anything particularly special, just running clight, although it is running through clight-gui, but the actual process is clight.

Please attach a Clight verbose log too!
