Release 2021.5
In this release, the sysroot code now ignores (with a log) any non-regular/non-symlink files in `/etc`. See: https://github.com/ostreedev/ostree/issues/2446
There are a few fixes and API additions for the new "ostree container" work happening in Rust in: https://github.com/ostreedev/ostree-rs-ext/
Some internal preparatory work landed for making an `AutoTransaction` API for C.
Finally, some small test suite improvements landed.
