[Libva] [intel-driver] remove fixed uses of inte-gen4asm tool

[Daniel Charles]

In the gen7 and gen8 post processing Makefiles the GEN4ASM
variable is not honored when calling intel-gen4asm. This causes
build errors when GEN4ASM is set to a different value

This was discovered when using intel-gpu-tools version 1.7 where
the shaders are actually compiled.
