It's not clear exactly what you want to do, but my guess is that you 
want clients to be given a netmask of 255.255.255.255, so that all 
traffic goes via the default route.

In that case, adding

dhcp-option=1,255.255.255.255

should  work. 1 is the DHCP option number for the netmask DHCP option, 
and setting this explicitly will override that default value which 
dnsmasq sends otherwise.
