package/util-linux: improve host build failure fix

As suggested by Peter Seiderer package util-linux doesn't need raw support
when built for host, so let's remove:
HOST_UTIL_LINUX_POST_PATCH_HOOKS += UTIL_LINUX_FIX_DISK_UTILS_COMPILE
in favor of:
HOST_UTIL_LINUX_CONF_OPTS += --disable-raw
This is a better approach than my commit:
