package/libkrb5: security bump to version 1.18.3

Fixes the following security issues:

- CVE-2020-28196: MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before
  1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message
  because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite
  lengths lacks a recursion limit.

Also fix .hash file indentation.
