python*: set thread stack size on musl

Ensure recursion limit is reached before stack overflow. Python does this for OSX and BSD: https://github.com/python/cpython/blob/13ff24582c99dfb439b1af7295b401415e7eb05b/Python/thread_pthread.h#L22 Size of 1MB chosen to match value in Alpine: https://git.alpinelinux.org/cgit/aports/commit/main/python2/APKBUILD?id=2f35283fec8ec451fe5fb477dd32ffdcc0776e89 Manual testing via Alpine's test-stacksize.py crashes on these previously, and works with these changes.
