Subject: [PATCH] data: don't send change updates for login-history

The login-history property of user objects can be quite large.
If wtmp is changed frequently, that can lead to memory fragmentation
in clients.

Furthermore, most clients never check login-history, so it's
wasted memory and wasted cpu.

This commit disables change notification for that property.  If
a client really needs to get updates, they can manually refresh
their cache when appropriate.
