eval: Reap zombies after built-in commands and functions
Currently dash does not reap dead children after built-in commands
or functions.  This means that if you construct a loop consisting
of solely built-in commands and functions, then zombies can hang
around indefinitely.

This patch fixes this by reaping when necessary after each built-in
command and function.
