In order to create symlinks on Windows, SeCreateSymbolicLinkPrivilege is an account privilege that is required to be held by the user. Not only must the privilege be enabled for the account, the activated privileges for the currently running application must be adjusted to enable the requested privilege. Rather than exposing an additional function to be called prior to the user's first os.symlink call, we handle the AdjustTokenPrivileges Windows API call internally and only expose os.symlink when the privilege escalation was successful. Due to the change of only exposing os.symlink when it's available, we can go back to the original test skipping methods of checking via `hasattr`.
