lakitu: Inherit cros-workon for all kernel ebuild files.

We use "cros_mark_as_stable" for automatically updating the kernel
ebuild files. The binary has a dependency on checking whether the ebuild
is inheriting "cros-workon.eclass" or not. In case it doesn't inherit
the eclass, the process will not treat the ebuild for uprev and will
create an error if it is "9999" ebuild as "9999" ebuild by ChromeOS
concept should be cros-workon ebuilds.
