Nguyễn Thái Ngọc Duy c0e40a2d66 send-pack.c: move async's #ifdef NO_PTHREADS back to run-command.c ...

On systems that do not support multithread, start_async() is
implemented with fork(). This implementation details unfortunately
leak out at least in send-pack.c [1].

To keep the code base clean of NO_PTHREADS, move the this #ifdef back
to run-command.c. The new wrapper function async_with_fork() at least
helps suggest that this special "close()" is related to async in fork
mode.
