Ron Yorston 098cd7ece4 ash: improve trap and jobs builtins in child shells 
The trap and jobs builtins can be used to report information about
traps and jobs.  This works when they're called from the current
shell but in a child shell the required information is usually
cleared.  Special hacks allow:

- trap to work with command substitution;
- jobs to work with command substitution or in a pipeline.

Neither works with process substitution.

- Relax the test for the trap hack so it also supports pipelines.

- Pass the command to be evaluated to forkshell() in evalbackcmd()
  so trap and jobs both work with process substitution.
