Bug#925901: caffe-contrib: build-depends on GCC 7

caffe-contrib build-depends on GCC 7. Please switch to GCC 8, so that 
buster doesn't need to ship with GCC 7.

nvidia-cuda-toolkit 10.1.105-1, supporting GCC 8,  has been uploaded to 
experimental (currently in NEW) and an unblock request for buster has 
been filed (#924070).
