[Python] failures in `test_compute.py::test_round_temporal` in conda-forge for linux aarch64/ppc64le

### Describe the bug, including details regarding any error messages, version, and platform.

A while ago, all branches of the pyarrow builds in conda-forge started failing with the following kind of errors. It only happens on linux-{aarch64,ppc64le}, so may be emulation related. Some of them look potentially tzdb-related (so maaaaybe related to https://github.com/conda-forge/linux-sysroot-feedstock/pull/66), but for the differences <1h, it seems unlikely to be the cause.
