UBUNTU: SAUCE: Add missing CPUID_7_EDX defines

BugLink: https://bugs.launchpad.net/bugs/1791080

The 4.4.144 backport of this patch adds the bit definitions
for two AVX-512 features: X86_FEATURE_AVX512_4VNNIW and
X86_FEATURE_AVX512_4FMAPS.
Those bits were not defined before in 4.4, but pick them up
to be in sync with upstream stable.
