The `make rpm-build` started failing with
```
find-debuginfo: starting
Extracting debug info from 1 files
*** ERROR: No build ID note found in /build/src/artifacts/rpmbuild/BUILD/zrepl-v0.6.1.47.gbae2bd2-build/BUILDROOT/usr/bin/zrepl
error: Bad exit status from /var/tmp/rpm-tmp.bYHLzG (%install)
```
This must be a change in Fedora (prob new Fedora major release).
Seize the opportunity to
1. stop building from `:latest`, and
2. build with an LTS RPM distro to improve zrepl RPM compatibility (no
problems so far AFAIK but this seems sensible)
fixes build failure for aarch64
