Makefile.in: Allow extra make flags to be passed to the kernel

It can be useful to pass additional flags to sub-make run in the kernel's source tree. For example, you might want to adjust the warning levels or modify some behavior of the kernel's Makefiles. To enable this ability, when input-wacom is built with an EXTRA_MAKEFLAGS variable set, its contents will be passed to the sub-make. For example, to enable additional kernel warnings, you can now call the input-wacom make as follows: `$ make W=123` Signed-off-by: Jason Gerecke <[email protected]>
