buildRustCrate: set NUM_JOBS to NIX_BUILD_CORES
Bofore this change, NUM_JOBS was set to 1. Some crates for building C/C++ code (e.g. the cc and cmake crates), rely on this variable to set the number of jobs. As a consequence, we were compiling embedded libraries serially. Change this to NIX_BUILD_CORES to permit parallel builds.
