package/squid: security bump to version 4.17

Fixes the following security issue:

- SQUID-2020:12 Out-Of-Bounds memory access in WCCPv2
  (CVE-2021-28116 aka ZDI-CAN-11610)

  Due to an out of bounds memory access Squid is vulnerable to an
  information leak vulnerability when processing WCCPv2 messages.

  This problem allows a WCCPv2 sender to corrupt Squids list of
  known WCCP routers and divert client traffic to attacker
  controlled routers.

  This attack is limited to Squid proxy with WCCPv2 enabled and
  IP spoofing of a router IP address configured as trusted in
  squid.conf.
