[PATCH 2/5] daemon.c run_service(): replace signal() with sigaction()

[Jeremiah Mahler <jmmahler@gmail.com>]

From signal(2)

  The behavior of signal() varies across UNIX versions, and has also var‐
  ied historically across different versions of Linux.   Avoid  its  use:
  use sigaction(2) instead.  See Portability below.

Replaced signal() with sigaction() in daemon.c run_service()
