stubby: makefile and init script cleanup

Reordered Makefile according to
https://github.com/openwrt/packages/pull/9399#issuecomment-508727872 .

Added PKG_BUILD_PARALLEL for faster compilation.

Remove duplicated conffiles section.

Install /etc/config/stubby using INSTALL_CONF, as is done elsewhere

Run init script through shellcheck and clean it up.

Added chmod for the stubby config file, to fix a LuCI issue.
