lib: extend render() to support function values

Extend the `render()` function to accept a function value as first argument,
which allows running arbitrary ucode functions and capturing their output.

This is especially useful in conjunction with `loadfile()` or `loadstring()`
to dynamically compile templates and rendering their output into a string.
