    build: ensure absolute path to sysprof dbus interface dir
    
    We want sysprof's exact datadir for compatability with
    platforms where software is installed into their own
    individual immutable prefix's. Such that, mutter's prefix will
    never equate to sysprof's. This depends on a MR in sysprof [0]
    which adds datadir to its pkgconfig files, as these files will always
    have the proper path we want.
    
    This adds version a constraint on sysprof_dep, as datadir was added to
    the .pc in this version.
