Fix segmentation fault in AVX2 builds

Enabling the AVX2 instruction set causes a segmentation fault in mocked
manifold tests. This is due to Eigen vectors stored in a std::shared_ptr
for which the memory allocated by gmock is not aligned even though it is
expected to be by Eigen for correct use of packet math.

The problem does not occur if Ceres is compiled with C++17 (or later)
enabled due to the support for aligned new allocations.
