* feat(Unwrap): allow <go1.13 can use Unwrap
`Unwrap` just use type assert, it doesn't need go1.13 actually

* test: add go1.13 errors compatibility check
Signed-off-by: Sherlock Holo <sherlockya@gmail.com>
* refactor(Unwrap): don't allow <go1.13 use Unwrap
If we implement Unwrap ourselves, may create a risk of incompatibility
if Go 1.14 subtly changes its `Unwrap` implementation.
<go1.13 users doesn't have `Is` or `As`, if they want, they will use
xerrors and it also provides `Unwrap`
