core: Private*/Protect* options with RootDirectory
When a service is chrooted with the option RootDirectory=/opt/..., then the options PrivateDevices, PrivateTmp, ProtectHome, ProtectSystem must mount the directories under $RootDirectory/{dev,tmp,home,usr,boot}. The test-ns tool can test setup_namespace() with and without chroot: $ sudo TEST_NS_PROJECTS=/home/lennart/projects ./test-ns $ sudo TEST_NS_CHROOT=/home/alban/debian-tree TEST_NS_PROJECTS=/home/alban/debian-tree/home/alban/Documents ./test-ns
