eval: Use the correct expansion mode for fd redirection
It has been reported that
echo test >&$EMPTY_VARIABLE
causes dash to segfault. This is a symptom of the bigger problem
that dash tries to perform pathname expansion as well as field
splitting on the word after >& and <&. This is wrong and this
patch fixes it to use the same expansions as done on a normal
redirection.
