[wasm2c] Fix alternate stack deallocation (#2466)
This makes `wasm_rt_init()` properly reentrant. By setting `g_alt_stack
= NULL`, we allow execution to continue beyond [wasm-rt-impl.c L171
](https://github.com/WebAssembly/wabt/blob/main/wasm2c/wasm-rt-impl.c#L171)
in `os_allocate_and_install_altstack`.
Applies to debug builds only due to `assert`.
