Fix transit path validation CVE-2017-6594
Commit f469fc6 (2010-10-02) inadvertently caused the previous hop realm
to not be added to the transit path of issued tickets. This may, in
some cases, enable bypass of capath policy in Heimdal versions 1.5
Note, this may break sites that rely on the bug. With the bug some
incomplete [capaths] worked, that should not have. These may now break
authentication in some cross-realm configurations.
Fix is present in >=7.4.0 source.
