Fix(CI): fix pyabacus link error and CMake CMP0177 policy

pyabacus/src/hsolver/CMakeLists.txt: add psi_paging.cpp to diagopack
library sources. Fixes undefined symbol get_cpu_pointer_safe which is
defined in psi_paging.cpp.

CMakeLists.txt: set CMP0177 to OLD to suppress install() DESTINATION
path normalization warning with CMake >= 3.31 when -Werror=dev is used.
This fixes the 'Integration Test' Configure step failure.
