Move date to build string in conda recipe (#441)

This PR moves the date string from the version to the build string for conda recipes in this repository.

This is necessary to ensure that the conda packages resulting from PR builds can be installed in the same environment as nightly conda packages, which is useful for testing purposes.

Additionally, this prevents a bug from occurring where the Python builds fail because the date string it computes is different than the one computed by the C++ build, therefore causing the Python build to search for a C++ build artifact that doesn't exist.
