volser doesn't depend on tviced, but on vlserver

Nothing within the volser/ directory depends on tviced, so remove the
unecessary dependency. Add an explicit dependency on vlserver, so that
libvldb is available to us.

This is required to get rid of some potential circular loops when we
start including volser objects in libafsauthent
