`gst/analytics/analytics.h` includes `gst/analytics/gstanalyticssegmentationmtd.h`,
which in turn `gst/video/video-info.h` but `gst-video-1.0` was only listed
in `Requires.private` field of `gst-analytics-1.0.pc`.
This would cause projects linking against `gst-analytics-1.0.pc` to fail to find
the headers when using alternative interpretation of pkg-config specification
that only considers private dependencies for include path during static builds,
such as the case e.g. on Nix.
