lib/repo: Add min-free-space-percent option, default 3% For ostree-as-host, we're the superuser, so we'll blow past any reserved free space by default. While deltas have size metadata, if one happens to do a loose fetch, we can fill up the disk. Another case is flatpak: the system helper has similar concerns here as ostree-as-host, and for `flatpak --user`, we also want to be nice and avoid filling up the user's quota.

tests/installed: Use temporary directories more consistently This is prep for splitting off "nondestructive" tests which we can run in parallel from the destructive/invasive ones which e.g. change the host refspec, do deployments. The `cd` invocation in `prepare_tmpdir` wasn't working because we were running it in a subshell. Fix this by dropping the subshell.
