wireguard: do not use -O3
commit cc5060ca0285efe2728bced399a1955a7ce808b2 upstream.
Apparently, various versions of gcc have O3-related miscompiles. Looking
at the difference between -O2 and -O3 for gcc 11 doesn't indicate
miscompiles, but the difference also doesn't seem so significant for
performance that it's worth risking.
