netutils/libshvc: update to correct reply head for non single element CID array

The update enables interoperability with a Silicon-Heaven
SHV3 protocol broker implemented in Rust language

New commits from shv-libs4c project

  https://github.com/silicon-heaven/shv-libs4c

- shv_pack_head_reply: correct reply head for non single element
  CID array

  When servicing request from the SHV3 protocol version broker
  itself then CID array is empty and missing TAG_CALLER_IDS
  for empty array breaks encoding scheme.

- shv_process: even in case of unsuccessful attempts to connect
  respect request to stop

  The request to stop initiate  by signal caused the high priority
  thread to enter busy-loop and block a system. Check for request
  to stop (running flag cleared) even in disconnected state after
  unsuccessful attempt.
