Revamp pacman signal handler

* All errors now go to stderr, so do the same here and simplify the
  writing of the error message.
* Add SIGHUP to the handled signal list, and don't repeat code.
* Attempt to release the transaction (e.g. remove the lock file)
  for all of HUP, INT, and TERM. Signals HUP and INT respects
  transaction state, TERM will immediately terminate the process.
