flag-o-matic.eclass: add -O3 to ALLOWED_FLAGS (strip-flags whitelist)
-O3 is perfectly safe in the absence of UB. And with UB, -O2 and friends can
easily break with new compiler versions and such anyway.
In addition, I'd say that -O/-O1 is probably as risky as -O3 nowadays, if not
more, because if nothing else, you don't get a bunch of hardening.
