ci/build: use debugoptimized everywhere
What does this MR do and why?
ci/build: use debugoptimized everywhere
`debug` is using -O0, which is useful for the debugging, but gives us no
advantage in the CI. Also all distro builds are -O2 or -O3, and combination
with LTO/IPO is usually poorly tested by compiler developers.
Use -O2 and be happy.
