QID 750098: SUSE Enterprise Linux Security Update for squid (SUSE-SU-2021:1838-1)

This update for squid fixes the following issues: - update to 4.15: - cve-2021-28652: broken cache manager url parsing (bsc#1185918) - cve-2021-28651: memory leak in rfc 2169 response parsing (bsc#1185921) - cve-2021-28662: limit headerlookuptable_t::lookup() to badhdr and specific ids (bsc#1185919) - cve-2021-31806: handle more range requests (bsc#1185916) - cve-2020-25097: http request smuggling vulnerability (bsc#1183436) - 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)
