lib/util: add tfork()
triple-fork to avoid handling SIGCHLD in the parent.
This function is a workaround for the problem of using fork() in
library code. In that case the library should avoid setting a global
signal handler for SIGCHLD, because the application may wants to use its
own handler.
status_fd can be used to wait for the child to exit and get its exit
status.
