[fix](build) Fix Boost sigtimedwait compile error on macOS (#61285)
### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary:
macOS does not implement `sigtimedwait` despite declaring
`_POSIX_C_SOURCE >= 199309L`. Boost 1.81's `config.hpp` incorrectly
enables `BOOST_POSIX_HAS_SIGTIMEDWAIT` on macOS, causing compile
failures in `boost/process/detail/posix/wait_for_exit.hpp`.
This issue was newly exposed by the Python UDF feature (#59543), which
introduced the first usage of `boost/process.hpp` in the BE codebase via
the include chain:
`aggregate_function_python_udaf.cpp → python_udaf_client.h →
python_client.h → python_udf_runtime.h → boost/process.hpp`
This PR adds a thirdparty patch to exclude `__APPLE__` from the
sigtimedwait detection macro, so Boost falls back to its fork-based
`wait_for_exit` implementation. The patch is only applied on Darwin and
does not affect Linux builds.
