virsh-secret: Rename vshEventCallback to virshSecretEventCallback

The next patch will use it in virsh-completer.c for returning the name
list of secret events.

The patch code originally authored by Michal Privoznik, Please refer to
https://www.redhat.com/archives/libvir-list/2018-May/msg01022.html

I splitted it to 2 patches with tiny change.
