tablet-pad-leds: fix compiler warning when -Dlibwacom=false

Fix the warnings generated:

	../src/evdev-tablet-pad-leds.c:54:1: warning: unused function
	'pad_mode_toggle_button_new' [-Wunused-function]
	pad_mode_toggle_button_new(struct pad_dispatch *pad,
	^

	../src/evdev-tablet-pad-leds.c:194:1: warning: unused function
	'pad_group_new' [-Wunused-function]
	pad_group_new(struct pad_dispatch *pad,
	^

	../src/evdev-tablet-pad-leds.c:238:1: warning: unused function
	'pad_led_get_sysfs_base_path' [-Wunused-function]
	pad_led_get_sysfs_base_path(struct evdev_device *device,
	^

When building with Clang v15 and without libwacom:

	$ CC=clang CXX=clang++ meson builddir -Dlibwacom=false
