I'm not following this but something seems strange. Are you really saying that a program that is in /sbin will not work with /usr not mounted? That seems quite broken; the whole point of /sbin being separate from /usr/sbin was always that things would work without /usr. So it seems more reasonable to conclude that dhclient must be excluded from the sanitizer than that it should fail without /usr. (There's the whole issue of whether ISC dhclient is so big that it doesn't belong in sbin, switching to dhcpcd, etc., but those are separate issues.)
