eclass: Update cpu optimization support in kernel-2.eclass
This patch clean's up the logic when applying or dropping
the cpu optimization patch. This patch will also support
the applying of the gcc v8 patch which will eventually be
in genpatches and applied also via the 'experiemental' use
flag after this support is enabled.
