runtime: use default system stack size, not 64 kB, on non-cgo macOS
At least one libc call we make
(res_search, which calls _mdns_query and then mdns_item_call)
pushes a 64 kB stack frame onto the stack.
Then it faults on the guard page.
Use the default system stack size, under the assumption
that the C code being called is compatible with that stack size.
For #31705.
