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.
