[tracker] libtracker-sparql: Add vapi file for the C portions

[Carlos Garnacho <carlosg src gnome org>]

commit 1b312602920959649befce085fe5365b38370196

    libtracker-sparql: Add vapi file for the C portions
    
    Just like we do with girs, merge together the vapi for the C portions and
    the generated vapi for the vala bits. This allows using
    TrackerNamespaceManager and TrackerResource from vala code.
