krb5 commit [krb5-1.17]: Eliminate qualname.plin

https://github.com/krb5/krb5/commit/a0a13c7d8e601cc950422a8dcc898a812122946b
commit a0a13c7d8e601cc950422a8dcc898a812122946b
Author: Greg Hudson <[email protected]>

    Eliminate qualname.plin
    
    Rewriting the qualname Perl script to use getaddrinfo created an
    unchecked dependency on Perl 5.14.  Instead, remove the script and use
    the C program in tests/resolve for the kadmin and gssrpc test suites.
    
    (cherry picked from commit 2a852b1f3fb00c7d19f4dbfba76f5ff7ebccd2c7)
