Use DEPRECATED_SCANF macro for remaining C99-compliant scanf functions

When the commit

commit 03992356e6fedc5a5e9d32df96c1a2c79ea28a8f
Author: Zack Weinberg <zackw@panix.com>

    Use C99-compliant scanf under _GNU_SOURCE with modern compilers.

added the DEPRECATED_SCANF macro to select when redirections of *scanf
functions to their ISO C99 compliant versions should happen, it
accidentally missed doing it for vfwscanf, vwscanf, and vswscanf.

Tested for powerpc64le and with build-many-glibcs (i686-linux-gnu and
nios2-linux-gnu are failing with current master, and with this patch,
but I didn't see a regression).
