Colin Walters 5a0d3356ef treefile: Add exclude-packages
In FCOS we have a kola test that basically does `rpm -q python`.
It's...a bit silly to spawn a whole VM for this.  Ensuring that
some specific packages don't get included has come up in a few
cases.

I think FCOS/RHCOS at least will want to blacklist `dnf` for example.
And as noted above, FCOS could blacklist `python`.

One major benefit of doing this inside rpm-ostree is that one
gets the full "libsolv error message experience" when dependency
resolution fails, e.g. blacklisting `glibc` I get:

```
