return value of Type.String() for function type doesn't match Go's reflect pkg

[fxamacker]

Return value of Type.String() for function type doesn't match equivalent call using Go's reflect package.

The code snippet below produces:

• tinygo: func
• go1.22: func(int, string) (bool, error)

f := func(int, string) (bool, error) {
	return false, nil
}
rt := reflect.TypeOf(f)
fmt.Println(rt.String())

This happens using latest tinygo release

$ tinygo run ./local/
func
[pato@entente tinygo]$ go run ./local/
func(int, string) (bool, error)
[pato@entente tinygo]$ go version
go version go1.23.0 linux/amd64
[pato@entente tinygo]$ tinygo version
tinygo version 0.33.0 linux/amd64 (using go version go1.23.0 and LLVM version 18.1.2)
