Heads up: libnm-glib-vpn soname bump

[Dan Williams]

Hi,

In concert with (but a bit later than) the libnm-glib soname bump, we'll
be bumping the soname of libnm-glib-vpn.so to help out the Debian and
Ubuntu NetworkManager packagers.  This is not a direct ABI change to
libnm-glib-vpn.  Only NetworkManager and the NetworkManager VPN plugins
link to libnm-glib-vpn anyway, so this shouldn't have any real affect.

libnm-glib-vpn.so.0.0.0 -> libnm-glib-vpn.so.1.0.0
