client: fix handling of GRPC_GO_REQUIRE_HANDSHAKE=on to not interpret…

… as "hybrid" (#2603) 6cc789b made `envconfig.RequireHandshakeOn` the default when unspecified by environment variable, but missed a fallthrough leading to `GRPC_GO_REQUIRE_HANDSHAKE=on` specifying `envconfig.RequireHandshakeHybrid`. This change adds the missing fallthrough.
