tools/gn: fix race condition regression

ExecProcess was converted to use C++11 range-based for loops in
crrev.com/986113002, but in debug builds, std::vector<...>::iterator
allocates memory to track invalid uses.  However, because we're in a
fork() child process context, we can't allocate memory.

Using the STL at all past fork() is technically unsafe, but our
current usage at least works today.
