Previously, Postgres was built in 'tmp_install/build', and installed into 'tmp_install'. In the CI, the 'build' directory was included in the final neon.tar.zst artifact that includes all the necessary binaries. That was unnecessary, the intermediate build results are not needed, only the final binaries. Separate the build directory so that the Postgres build happens in 'build', and it is installed into 'tmp_install'. That makes the final neon.tar.zst artifact smaller. The changes to the python tests are needed to find the 'pg_regress' binary in the installation directory. Previously, they would use the 'pg_regress' binary from the build directory, not the final installation location.
