We're seeing some hangs while ostree is fetching updates.
I imagine the fact that SoupSessionAsync has no timeout by default
could be the cause of this.
Set timeout values to 60 seconds, which is the default for the new
SoupSession API which we may switch to later.

tmpfiles.d configurations generally require write access to some places
that are read-only until ostree-remount runs.
Make sure ostree-remount has run first.
Thanks to Cosimo Cecchi for finding and diagnosing this problem.
