core: skip ReadOnlyPaths= and other permission-related mounts on PermissionsStartOnly= (#5309) ReadOnlyPaths=, ProtectHome=, InaccessiblePaths= and ProtectSystem= are about restricting access and little more, hence they should be disabled if PermissionsStartOnly= is used or ExecStart= lines are prefixed with a "+". Do that. (Note that we will still create namespaces and stuff, since that's about a lot more than just permissions. We'll simply disable the effect of the four options mentioned above, but nothing else mount related.) This also adds a test for this, to ensure this works as intended. No documentation updates, as the documentation are already vague enough to support the new behaviour ("If true, the permission-related execution options…"). We could clarify this further, but I think we might want to extend the switches' behaviour a bit more in future, hence leave it at this for now. Fixes: #5308
