daemon: Fix regression of libvirtd reloading support
    
    This is introduced by commit df0b57a95a, which forgot to
    add signal handler for SIGHUP.
    
    A simple reproduce method:
    
    1) Create a domain XML under /etc/libvirt/qemu
    2) % kill -SIGHUP $(pidof libvirtd)
    3) % virsh list --all (the new created domain XML is not listed)
