PARQUET-656: Revert attempts to make conda artifacts portable

The toolchain issue is not tractable on an ad hoc basis. I suggest we use a consistent gcc toolchain across the CI environments for Parquet and Arrow, and we can post dev builds for human consumption / testing via conda-forge (where the RHEL devtoolset is there and already working well). Sound good @xhochy?
