package/shadowsocks-libev: security bump to version 3.3.4

- Fix CVE-2019-5163: An exploitable denial-of-service vulnerability
  exists in the UDPRelay functionality of Shadowsocks-libev 3.3.2. When
  utilizing a Stream Cipher and a local_address, arbitrary UDP packets
  can cause a FATAL error code path and exit. An attacker can send
  arbitrary UDP packets to trigger this vulnerability.
- Fix CVE-2019-5164: An exploitable code execution vulnerability exists
  in the ss-manager binary of Shadowsocks-libev 3.3.2. Specially crafted
  network packets sent to ss-manager can cause an arbitrary binary to
  run, resulting in code execution and privilege escalation. An attacker
  can send network packets to trigger this vulnerability.

Also update indentation in hash file (two spaces)
