virVBoxSnapshotConfSaveVboxFile: Don't modify deprecated 'xmlIndentTreeOutput'

'xmlIndentTreeOutput' is now deprecated by libxml2.

The default value set by libxml2 is '1', and the vbox driver resides
only inside the standalone daemon where the value will not be changed by
us thus there's no observable change in behaviour.
