squid: update to 5.7

* --sbindir is already defined in
  common/environment/configure/gnu-configure-args.sh

* --enable-useragent-log and --enable-referer-log are obsolete since
  version 3.2.0.4.

* --enable-arp-acl is gone
  (squid-cache/squid@41b9172011).

* --enable-carp is gone, CARP is compiled in
  (squid-cache/squid@b2ea838f69).

* --enable-truncate was removed upstream
  (squid-cache/squid@b3fb907032).

* squid_cv_gnu_atomics is replaced with c++11 std::atomic
  (squid-cache/squid@ddd4edb743).

* squid_opt_enable_large_files is the duplicate of --with-large-files.
  Apparently Juan RP (aka xtraeme) used this option back in 2016 to fix
  cross build for arm* and glibc. Now that squid builds completely fine
  without it, it is safe to assume this option is not needed anymore.

* define BUILDCXX properly (CXX_host cannot be set outside of
  functions).

* CVE-2018-1000027 was fixed since version 4.0.23.
