Fix deadlocks.

1. Close pipe fds[1] as soon as possible. Otherwise it may block when
   reading from fds[0] even though the child process has exited early
   and closed its copy of fds[1].

2. Waitpid after pipe is closed. Otherwise the screencap child process
   may block while writing fds[1], because the fds[0] is not closed
   yet. If we close fds[0] first, then the screencap child process will
   die because of SIGPIPE, and waitpid will return correctly.
