Version of Singularity

4.1.0 and above

Describe the bug

When FUSE mounts fail (e.g. by symlinking squashfuse_ll to /bin/false):

$ singularity run --oci docker://alpine
INFO:    Using cached OCI-SIF image
ERROR:   While removing temporary bundle: failed to delete config.json file: remove /usr/local/var/singularity/mnt/session/oci-bundle1146451062/config.json: no such file or directory

fix: oci: fallback to tmp-sandbox from docker://
e8d0886 
When FUSE mount fails, ensure fallback to a temporary sandbox bundle is
successful for OCI image sources (e.g. docker://...)

A selection of small fixes accomplishes this...

* Ensure platform is set in the transport options used during fallback.
* Use a new launcher instance for fallback Exec, as launcher has some
  state.
* Correctly set the image config for native bundles.

Also:

* Remove unused imgcache handle in actions code.
* Remove unused manifest obtained in native bundle code.

Fixes sylabs#3100
