Fix SIGSEGV in gtest death tests due to small stackHEADmaster

In https://github.com/google/googletest/blob/v1.14.0/googletest/src/gtest-death-test.cc#L1307
on x86-64 gtest sallocates 8192 bytes for `clone`:

```
static pid_t ExecDeathTestSpawnChild(char* const* argv, int close_fd) {
    const auto stack_size = static_cast<size_t>(getpagesize() * 2);
    ...
    child_pid = clone(&ExecDeathTestChildMain, stack_top, SIGCHLD, &args);
```

After that attempt to call execv is intercepted by libsandbox.so, which
allocates 8192 + more bytes multiple times on stack, causing SIGSEGV
(instead of expected types of crashes).

This PR moves all allocations for related function to heap, so now
call path fits `getpagesize() * 2` with large margin.
