python3-pydantic-core: fix TMPDIR path reference

Backport a new upstream fix to remove the TMPDIR
reference from the rust code.

Signed-off-by: Frank de Brabander <debrabander@gmail.com>

We've seen TMPDIR [build-paths] contamination in the
built pydantic_core/_pydantic_core.cpython-*-*-linux-gnu.so

See discussion upstream in:
https://github.com/pydantic/pydantic-core/issues/1365

Backport fix from:
https://github.com/pydantic/pydantic-core/commit/e07c41b3bad75948201a2201387225694c2fb501

Similar to Styhead 6f0a41130c0dcf80e22f6f3fd93d39369c235693, but for 2.18.4
