sagemathgh-39111: build/pkgs/planarity/spkg-configure.m4: update head…

…er check

In the `./configure` test for libplanarity, we should be testing for
`planarity/graph.h` instead of `planarity/planarity.h`:

  1. `graph.h` is what we actually use in
`src/sage/graphs/planarity.pyx`,
  2. `planarity.h` is going away in a future version.

cf. https://github.com/graph-algorithms/edge-addition-planarity-
suite/pull/125
