lib/commit: Fix a tmpfile fd leak in static delta processing
I had thought `glnx_link_tmpfile_at()` actually consumed the tmpfile;
it does consume the *path* but not the fd. In the non-delta path
things were fine since we used the autocleanup.
But the delta code had a tmpfile allocated in its struct that got reused, and
hence leaked the fd. Fix this by making the commit API actually consume the
tmpfile fully, just like the path path.

The main use case I'm targeting this for is the Fedora Atomic Host installer

we can still use the local repo as an object cache, since we have it sitting

caller of `ostree_repo_write_metadata_stream_trusted()` which was the dumb
function mentioned.

lib/checkout: Ignore world-writable dirs for bare-user-only checkout
See https://github.com/ostreedev/ostree/pull/909 for more information on the
rationale. Basically there's no reason for flatpak (which uses `bare-user-only`)
to have world-writable dirs. Particularly with the presence of the system
helper.
An approach I considered instead was to parse and validate directory metadata
objects at commit time. We still may do that in addition; for file objects we *had*
to do it that way because the actual files would be laid down suid. But directories
live only as inert `.dirmeta` objects until we do a checkout (i.e. `mkdir()`), so
we can solve the problem at checkout time.

lib/commit: Drop some conditionals/clarify code in content path
Both callers of `commit_loose_object_trusted()` were passing
`OSTREE_OBJECT_TYPE_FILE`, so drop that parameter. This in turn
allows us to drop lots of checking of that inside the function.
Add a doc comment, and rename to `commit_loose_content_object()` for clarity.

lib/commit: Port final object writing function to new code style
I noticed my previous patches incorrectly started doing `return glnx_throw*`
inside a `goto out;` function. Fix this by porting forward consistently to new
style. We just do the error prefixing in the caller.
