cmatrix: Improve reproducibility patch to handle libdir!=/usr/lib

The upstream code basically hard-code libdir to /usr/lib. This was
hidden by the upstream non-reproducible path existence check.

Improve the reproducibility patch to use the cmake variables derived
from $libdir and $datadir :
CMAKE_INSTALL_LIBDIR and CMAKE_INSTALL_DATAROOTDIR.
