torture: Add testing of RCU's Rust bindings to torture.sh 



This commit adds a --do-rcu-rust parameter to torture.sh, which invokes
a rust_doctests_kernel kunit run.  Note that kunit wants a clean source
tree, so this runs "make mrproper", which might come as a surprise to
some users.  Should there be a --mrproper parameter to torture.sh to make
the user explicitly ask for it?
