Weird copr-builder error

[praiskup]

This happened for multiple builds after the system-recovery (so not a normal
situation):

But anyway, we should never end up with failed builds like that. Users have to
retrigger builds, etc.

Triage: The builder-live.log didn't exist, so we shouldn't have tried to gzip it. Maybe some retry should have happened.
