This is not going to work in busybox shell:
   option domain-name-servers ${dns/ /,};

# test="a b c"
# echo ${test/ /,}
/bin/sh: syntax error: bad substitution

Suggest you use a function, something like:
comma_separate() {
	echo "$1" | sed "s/ /,/g"
}

and then use:
   option domain-name-servers $(comma_separate "$dns");

And the same substitution should be made for ntp servers, which can also 
have multiple values.
