sh: Set $? to 0 for background commands.

For backgrounded pipelines and subshells, the previous value of $? was
being preserved, which is incorrect.

For backgrounded simple commands containing a command substitution, the
status of the last command substitution was returned instead of 0.

If fork() fails, this is an error.
