wget: rank wget-nossl below uclient-fetch for the wget alternative

apk uses whatever /usr/bin/wget resolves to for HTTPS index downloads.
wget-nossl's alternative was ranked 300, above the HTTPS-capable
uclient-fetch (200), so pulling it in transitively silently broke
apk update. Lower it to 100 so uclient-fetch keeps the default while
wget-nossl stays selectable. wget-ssl (400) is unchanged.
