[pmg-devel] [PATCH pmg-api] cluster: fingerprint parsing: adapt to changed openssl output

[Stoiko Ivanov <s.ivanov@proxmox.com>]

currently updating the fingerprints using `pmgcm update-fingerprints`
runs into an error indicating that parsing of the remote node's
fingerprint fails

The error is due to changed output in openssl's x509 command,
introduced in commit:
91034b68b39e3525f09fb263b9272de410a3ba4c
in openssl upstream [0]

Note that in that case it would equally work to change the parameter
from `-sha256` to `-SHA256` in the `openssl x509` command above

The change seems small enough to warrant pulling it into stable-7 as
well (although the issue should not occur in systems upgraded
according to our howtos).
