configure: fix vdpau test if vdpau is disabled/unavailable

The check for HAVE_AV_CODEC_NEW_VDPAU_API just determines whether the
new vdpau libavutil pixel format is available (which implies presence of
the new API). However, that pixel format (and the correspondig config
test define) is also used in generic code (compiled even without vdpau)
in fmt-conversion.c. Since the configure test didn't define the symbol
if vdpau was not available, it broke in this case.
