Title: #5766: Sources cleanup - part 3.
* patch `sss2krb5_error()` to translate `ENOENT` to `KRB5_CC_NOTFOUND`. Result will
be different output:
klist: Matching credential not found
-- looks a little bit better, but I'm not sure this conversion is a right thing in
other possible scenarios
Added a patch to implement this option.
