nbd: re-introduced linking with -lrt, and added an additional -lpthread on top of it

Browse source 
Linking these libraries makes sure that they can be found at run-time,
because a proper rpath into the Nix store is added to the generated
executable. Without that rpath, nbd-server will try to load the system's
libpthread.so.0, which may not be what we want.
