posix: Fix some crashes in wordexp [BZ #18096]
Without these fixes, the first three included tests segfault (on a NULL dereference); the fourth aborts on an assertion, which is itself unnecessary. Signed-off-by: Julian Squires <julian@cipht.net> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
