    libtracker-sparql: Check for the correct build CWD as subproject
    
    When building Tracker as a subproject, the CWD at build time is still
    that of the root project. We want to check this, instead of the
    subproject build root.
    
    This makes the remote module correctly detected in the build dir
    when building Tracker as a subproject (as it happens in tracker-miners
    CI).
