jobs: Only block in waitcmd on first run
This patch ensures that waitcmd never blocks unless there are
outstanding jobs.  This could otherwise trigger a hang if children
were created prior to the shell coming into existence, or if
there are backgrounded children of other kinds (e.g., a here-
document).
