Description: Lack of support of HTTP/2 by default starts to hurt, for example with https-dns-proxy package, some DoH resolvers (like mullvad) no longer support HTTP/1 and are not usable. This enables HTTP/2 support by default (which would bring ~68Kb libnghttp). Signed-off-by: Stan Grishin <stangri@melmac.net>lilik-openwrt-22.03
