HID: logitech: Add depends on LEDS_CLASS to Logitech Kconfig entry

Commit 97b741a ("HID: lg-g15: Add keyboard and LCD backlight control")
makes the hid-lg15 kernel module, which gets configured through config
HID_LOGITECH depends on symbols from the led class. Add a depends on
LEDS_CLASS to HID_LOGITECH to avoid undefined reference errors on the
led class symbols.
