FindCUDA: Only depend on Threads::Threads on platforms that need it

Browse Source 
In commit 46371132b3 (FindCUDA: CUDA_LIBRARIES doesn't contain raw
`-pthread`, 2019-11-11, v3.17.0-rc1~455^2) we introduced use of the
`Threads::Threads` target, but we do not `find_package(Threads)` on all
platforms.  Use the target only if it exists.
