Default multipath: move bindings file location

The current bindings file location (/var/lib/multipath/bindings) can be
problematic, since multipath can start up before /var/lib is mounted yet in
late boot. In this case, multipath will create it's own bindings file which
will be covered up by /var when it is mounted. This means that the device
names that you get on startup might be different from the device names that you
get when you run multipath on a system during normal operation. Since /etc is
always available when multipath starts up in late boot, moving the bindings
file there fixes the problem.
