cmake: re-add two missing includes

Previously these were were included transitively via `cmake/ExtractValidFlags.cmake`. ngtcp2#964 deleted that file. The replacements it added pulled these includes after the local code uses them. Re-add these includes into the `CMakeLists.txt` that uses them. Fixes ngtcp2#979
