test: fix compiler warning when -Dlibwacom=false

Fix the warning generated:

	[129/243] Compiling C object libinput-test-suite.p/test_test-touchpad.c.o
	../test/test-touchpad.c:2679:1: warning: unused
	function 'touchpad_has_rotation' [-Wunused-function]
	touchpad_has_rotation(struct libevdev *evdev)
	^

When building with Clang v15 and without libwacom:

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