[fix] remove variadic flag from functions

response:stream-binary and util:get-fragment-between are both
non-variadic.

fn:namespace-uri were flagged as non-variadic, which is the default.

Note: there are variadic functions in the range module. Removing the flag results in failing tests, so it seems they
really need to be variadic.
