[PATCH proxmox-backup 4/5] api: s3: drop unused rpcenv parameter from bucket listing

[Erik Fastermann <e.fastermann@proxmox.com>]

The bucket listing never touched the RPC environment, and the API
macro does not require handlers to accept one. Dropping it allows
callers without an RPC environment to use the function directly.

No functional change intended.
