ci: Enable LTO for fedora-release job

Requires -Wno-error=... to be passed to the linking stage.

NOTE: This does not imply that it's safe to enable LTO for Fedora
package builds yet. It just helps prevent moving further away from that
long term goal.

v2:
* Keep passing -Wno-error=array-bounds & -Wno-error=stringop-overread.
