…unwrap" Using errors.Unwrap() is not the best thing to do, since it returns nil in case of an error which was not wrapped. More to say, errors package provides more elegant ways to check for underlying errors, such as errors.As() and errors.Is(). This reverts commit f8e1388, reversing changes made to 6ca9d8e.

Make use of errors.Is() and errors.As() where appropriate to check the underlying error. The biggest motivation is to simplify the code. The feature requires go 1.13 but since merging opencontainers#2256 we are already not supporting go 1.12 (which is an unsupported release anyway). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>

My previous attempt (#2280) was a bit immature (though it worked).

Revert #2280, and use errors.Is() and errors.As()
