DAOS-18742 rebuild: Ignore destroyed containers during migration

[mchaarawi]

If a container still exists locally but the remote fetch returns DER_CONT_DESTROYING or DER_CONT_NONEXIST, the error is unexpectedly stored in mpt_status and causes rebuild to fail.

A similar issue can happen during punch, so ignore these container-gone errors there as well.

Steps for the author:

• Commit message follows the guidelines.
• Appropriate Features or Test-tag pragmas were used.
• Appropriate Functional Test Stages were run.
• At least two positive code reviews including at least one code owner from each category referenced in the PR.
• Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

• Gatekeeper requested (daos-gatekeeper added as a reviewer).
