linux-info.eclass: sync with upstream Gentoo

Browse Source 
Mostly cosmetic changes here, but kernel_is gets optimized a bit.
Very few packages actually use this eclass.  Mostly updating this
so we can pull in a newer kernel-2.eclass.

BUG=chromium-os:14334
TEST=`emerge fuse udev qemu-kvm` still works
TEST=`cbuildbot chromiumos-sdk` worked
TEST=`cbuildbot amd64-generic-full` passes
TEST=`cbuildbot arm-generic-full` passes
TEST=`cbuildbot x86-generic-full` passes
TEST=build_packages+build_image for x86-alex boots
