Fix failure to cleanup wide stream buffers in preparation for BZ#16734 fix

Greetings,

In preparation for BZ#16734 fix, I've build libc with (not intended to commit):

diff --git a/libio/libioP.h b/libio/libioP.h
index d8604ca..d1699de 100644
--- a/libio/libioP.h
+++ b/libio/libioP.h
@@ -719,7 +719,7 @@ extern _IO_off64_t _IO_seekpos_unlocked (_IO_FILE
*, _IO_off64_t, int)
 # endif
 #endif

-#if _G_HAVE_MMAP
+#if _G_HAVE_MMAP && 0

 # include <unistd.h>
 # include <fcntl.h>
... etc.

This results in mtrace test failure:
FAIL: misc/tst-error1-mem

Attached patch fixes the test failure.

Thanks,
