shadowsocks-client: remove

It hasn't been maintained for years and doesn't have recent features such as AEAD crypto and IPv6.
(The "recent" update is fix compilation without deprecated OpenSSL APIs, which is made by Rosen Penev)
It has been superseded by shadowsocks-libev, which is recently maintained by community and has LuCI frontend.
Despite its smaller size, it depends on OpenSSL, which is way larger than MbedTLS, the one shadowsocks-libev used. Thus, it doesn't really fit in space-constrained devices.
