• Handle more partial responses (bsc#1185923)
• fix previous change to reinstante permissions macros, because the wrong
  path has been used (bsc#1171569).
• use libexecdir instead of libdir to conform to recent changes in Factory
  (bsc#1171164).
• Reinstate permissions macros for pinger binary, because the permissions
  package is also responsible for setting up the cap_net_raw capability,
  currently a fresh squid install doesn’t get a capability bit at all
  (bsc#1171569).
• Change pinger and basic_pam_auth helper to use standard permissions.
  pinger uses cap_net_raw=ep instead (bsc#1171569)
