tomoyo: Do not generate empty policy files
The Makefile automatically generates the tomoyo policy files, which are not removed by make clean (because they could have been provided by the user). Instead of generating the missing files, use /dev/null if a given file is not provided. Store the default exception_policy in exception_policy.conf.default.
