util-linux: disable useless programs in the host package

Disable all programs that depend on ncurses, as well as utilities that
are useless on the host: agetty, chfn-chsh, chmem, login, lslogins,
mesg, more, newgrp, nologin, nsenter, pg, rfkill, schedutils, setpriv,
setterm, su, sulogin, tunelp, ul, unshare, uuidd, vipw, wall, wdctl,
write, zramctl.

Also add dependency on host-zlib if host cramfs utils are to be built.
