cloudinit.GenerateLocalData: drop ineffectual assignment
cloudinit.GenerateLocalData: drop ineffectual assignment

commit 68fe5efc2 changed the signature of cloudInitIsoFunc() and dropped
the inFiles array from it. However, it kept building the files array in
cloudinit.GenerateLocalData ineffectually.

This change drops the needless `files` variable.

Thanks to Ezra Silvera for pointing this out.
