openSUSE 15-SP3: 2021:1525-1 Moderate: Singularity Security Fix

This update for singularity fixes the following issues:

Update to 3.8.5:

- CVE-2021-41190: Fixed OCI manifest and index parsing confusion

(boo#1193273).

- Building Singularity from source requires go greater or equal 1.16. We

now aim to support the two most recent stable versions of Go. This

corresponds to the Go Release Maintenance Policy

- Sourcing a script based on PATH is now permitted, fixing a regression

introduced in 3.6.0.

- Environment variables in container definition files are properly scoped,

fixing a regression introduced in 3.8.0.

- Fix the oras contexts to avoid hangs upon failed pushes to Harbor

registry.
