ALT-PU-2016-2276: package `kernel-image-un-def` update to version 4.8.7-alt1

The x86_decode_insn function in arch/x86/kvm/emulate.c in the Linux kernel before 4.8.7, when KVM is enabled, allows local users to cause a denial of service (host OS crash) via a certain use of a ModR/M byte in an undefined instruction.
