bsc minimal: disable eth_getProof on dshackle upstream

Minimal BSC nodes lack the state to serve eth_getProof and return
"header not found" (especially while catching up after a restart). The
drpc gateway probes eth_getProof and marks the WHOLE upstream unavailable
on failure, so e.g. bsc-mainnet-bsc-minimal on us-32 showed unavailable in
US-East despite the node being online and at head.

Disable eth_getProof on bsc minimal upstreams only (network=bsc,
db_type=minimal) so they stay available for every other method. Archive/
pruned bsc and all other nodes keep serving getProof.
