you should not need to do that, we definitely do not have such scripts
in our official images:

ogra at dragonboard:~$ ls /lib/systemd/system/wcnss-start.service
ls: cannot access '/lib/systemd/system/wcnss-start.service': No such
file or directory

the module should be auto-loaded during boot (this happens surely for
us with the default ubuntu core images). there must be something wrong
with your setup ... 
here is a boot log from a default ubuntu core dragonboard image http://
paste.ubuntu.com/24006524/ there wcn36xx just gets auto-loaded, perhaps
you miss a kernel configuration ?

there is no ethernet device on a dragonboard, do you use an addon board
?
