modfile: fix crash on AddGoStmt in empty File

AddGoStmt uses File.Syntax without checking whether
it is nil or not. This causes crashes when using it on empty files that
have not had their Syntax member initialized to a valid pointer.

This change fixes it by ensuring File.Syntax is a valid pointer before
proceeding.

Fixes golang/go#62457.
