Use:
EXTRA_CFLAGS := -I$(src)/include/linux/sys
EXTRA_CFLAGS += -I$(src)/include/linux
EXTRA_CFLAGS += -I$(src)/include

[Sidenote - you should only need the second line. Files in include/sys
should be included as:
#include <sys/file.h>

And there should be no .h files in the linux directory].

EXTRA_CFLAGS are only relevant for the current kbuild Makefile - so
it does not make sense to add it to the top-level Makefile.
