wordexp: Explicitly pass along IFS.

Per Austin group issue #884, sh should not import IFS from the environment
but always set it to $' \t\n'. For wordexp(), however, it is documented and
useful for it to use IFS from the environment.

Since sh currently imports IFS from the environment, this change has no
functional effect.
