Bug 1308984

Description of problem:
There is a know issue with krb5 and inclusion of nonexistent files
BZ1274424. There is a workaround in fedora 23+ for issue with crypto-policies.
However the solution is not sufficient. Because old version of crypto-policies does not contain such file and therefore link can be broken.

And it's hard to explain someone that it's not enough to upgrade krb5-* to the latest version for fixing issues caused by broken symbolic link.

Therefore there shoudl be stricter requires on crypto-policies.

Version-Release number of selected component (if applicable):
sh$ rpm -qf /etc/krb5.conf.d/crypto-policies 
krb5-libs-1.14-7.fc23.x86_64

How reproducible:
Deterministic

Actual results:
The latest krb5-libs can be installed with old version of crypto-policies

sh$ rpm -q krb5-libs crypto-policies
krb5-libs-1.14-4.fc23.x86_64
crypto-policies-20150518-3.gitffe885e.fc23.noarch

sh$ file /etc/krb5.conf.d/crypto-policies 
/etc/krb5.conf.d/crypto-policies: broken symbolic link to /etc/crypto-policies/back-ends/krb5.config


Expected results:
krb5-libs has strict requires for crypto-policies which contains file /etc/crypto-policies/back-ends/krb5.config
and therefore update of krb5-libs will require update of crypto-policies as well
and will prevent issues with broken symbolic link.

Additional info:
You might use 
Requires: crypto-policies >= 20151104-1

or
Requires: /etc/crypto-policies/back-ends/krb5.config

sh$ rpm -q --whatprovides /etc/crypto-policies/back-ends/krb5.config
crypto-policies-20151104-1.gitf1cba5f.fc23.noarch
