minijail-tools: move constants.json from minijail It makes more sense to keep constants.json in the minijail package, because that's where the tool that consumes it, compile_seccomp_policy, lives. By having it in this package, we can set it as the default location for compile_seccomp_policy, which means it shouldn't ever even need to be specified on the command line (although it still can be). And we can hook into the cross-compilation machinery to get it to automatically use the constants for the right architecture. I've also changed from generating constants.json by running a test program in qemu-user to generating it from LLVM IR, which will save a huge QEMU build dependency.
