luci-app-ssr-plus: simplify libustream dependencies

By now, there're 3 variants in libustream, we just need one of them to
work with the SSL support for uclient-fetch.

The old dependencies implementation can cause confusing: users may
select any one of these variants as they don't really know which one
should be used, and when the one they selected differs from default,
the conflict will be up.

As OpenWrt has specified a default variant there already [1][2][3],
we just need check if this library is selected, with whichever variant.
If they really don't wanna use any of them, it's time to say goodbye :D
