Commit 12c7541 updated the opencontainers/selinux dependency to v1.3.1, which had a breaking change in the errors that were returned. Before v1.3.1, the "raw" `syscall.ENOTSUP` was returned if the underlying filesystem did not support xattrs, but later versions wrapped the error, which caused our detection to fail. This patch uses `errors.Is()` to check for the underlying error. This requires github.com/pkg/errors v0.9.1 or above (older versions could use `errors.Cause()`, but are not compatible with "native" wrapping of errors in Go 1.13 and up, and could potentially cause these errors to not being detected again.
