MAINTAINERS: add ABI headers to KHO and LIVE UPDATE

include/linux/kho is supposed to hold KHO headers.  Add it to KHO's
MAINTAINERS entry so the right people can get patches to it.

include/linux/kho/abi contains the live update ABI headers for LUO core
and memfd.  It will also hold ABI headers for other upcoming file types as
well.  Add it to live update entry so live update maintainers can get
changes for it (currently they happen to be the same people).
