fpsdisplaysink: check the sync property exists on embedded sink(s)

Follow-up on 4111d6321f, the video
sink(s) used by fpsdisplaysink might not have the sync property. So we
check its existence to avoid warning from g_object_set() at runtime.

Fixes #604280

/* FIXME:
* - can we avoid plugging the textoverlay?
* - we should use autovideosink as we are RANK_NONE and would not get plugged
* - We are using autovideosink now, but then sync doesn't work
* - but then we have to lookup the realsink to be able to set sync
* - or we could make autovideosink proxy the property
* - gst-seek 15 "videotestsrc ! fpsdisplaysink" dies when closing gst-seek
* - if we make ourself RANK_PRIMARY+10 autovideosink asserts
