Alexander Bokovoy ee7dfc3d29 Allow mod_auth_gssapi to create and access ccaches in /run/ipa/ccaches
With commit c6644b8566 we default to
create unique credential caches in /run/ipa/ccaches for every client
that connects to IPA with a new session. On F34, mod_auth_gssapi process
running as 'apache' cannot create the ccache in /run/ipa/ccaches because
it has no access rights.

The core of the problem is that we have two different paths to obtaining
a ccache: one where 'apache' running httpd process creates it directly
and one where an internal redirect from 'ipaapi' running httpd process
is happening.

Use SUID and SGID to 'ipaapi'/'ipaapi' and allow 'apache' group to write
to '/run/ipa/ccaches'. This fixes the problem.

Note that we cannot completely remove 'GssapiDelegCcachePerms'. If we'd
do so, mod_auth_gssapi will do redirects and fail.
