Cycles: Make curves modified by a taper object with modifier considered a deform modified

That might consider a bit more objects to be considered deform modified,
but it covers common case of using taper object without require of doing
recursive checks.

In worst case it'll be just some extra synchronization time, no render
time difference will happen for false-positive because of extra checks
happening in Cycles.
