Describe the bug

Wire can't handle functions with varargs.

To Reproduce

1. Add a varargs parameter to a function, see for example

google/go-cloud@7cfcbb8

2. Add a wire.Value entry to provide a concrete value for the parameter.

3. Run wire.

Expected behavior

The Go file generated by wire should compile, but it doesn't.
