2. test: avoid disk space warning for non-regtest

   feature_config_args.py incorrectly assumed that its testnet4 node
   would not log a disk space warning.
   
   0683b8ebf33386d5c05140df89df10b1853d7c7e increased m_assumed_blockchain_size
   on testnet4 from 1 to 11 GiB which triggers this bug on more
   systems, e.g. a RAM disk.
   
   Prevent the warning by setting -prune for these nodes.
   
   Fix the same issue in feature_signet.py
