Bart Van Assche a169500590 Makefiles: Use KBUILD_EXTRA_SYMBOLS instead of copying Module.symvers 
Copying Module.symvers is the oldest supported method for building external
kernel modules that depend on another external kernel module. Since support
for that method will be removed from Linux kernel v5.5, use
KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel
modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in
upstream kernel v2.6.26 so this patch drops support for kernels before
v2.6.26.
