update_headers.sh: arm64: Copy sve_context.h if available
The SVE KVM support for arm64 includes the additional backend
header <asm/sve_context.h> from <asm/kvm.h>.
So update this header if it is available.
To avoid creating a sudden dependency on a specific minimum kernel
version, ignore such optional headers if the source kernel tree
doesn't have them.
