9e48d7f562 hst/config: move container fields from toplevel
This change also moves pd behaviour to cmd/hakurei, as this does not belong in the hst API.

56aad8dc11 test/sandbox/tool: marker pathname from flag
Since this is going to be placed in a shared directory, it needs to be unique to the identity. Instead of trying to figure out identity from mountinfo, just have the test script pass hardcoded values.

4cf694d2b3 hst: use hsu userid for share path suffix
The privileged user is identifier to hakurei through its hsu userid. Using the kernel uid here makes little sense and is a leftover design choice from before hsu was implemented.

c9facb746b hst/config: remove data field, rename dir to home
There is no reason to give the home directory special treatment, as this behaviour can be quite confusing. The home directory also does not necessarily require its own mount point, it could be provided by a parent or simply be ephemeral.

22d577ab49 test/sandbox: do not discard stderr getting hash
This is the first hakurei run in the test, if the container outright fails to start this is often where it happens, so throwing away the output is very unhelpful.

83a1c75f1a app: set up acl on X11 socket
The socket is typically owned by the priv-user, and inaccessible by the target user, so just allowing access to the directory is not enough. This change fixes this oversight and add checks that will also be useful for merging security/hakurei#1.

38245559dc container/ops: mount dev readonly
There is usually no good reason to write to /dev. This however doesn't work in internal/app because FilesystemConfig supplied by ContainerConfig might add entries to /dev, so internal/app follows DevWritable with Remount instead.

387b86bcdd app: integrate container autoroot
Doing this instead of mounting directly on / because it's impossible to ensure a parent is available for every path hakurei wants to mount to. This situation is similar to autoetc hence the similar name, however a symlink mirror will not work in this case.
