[bug-inetutils] ftpd and noisy 530 errors

[Alfred M. Szmidt]

This supposedly "prevents ftpd to display noisy 530 error message.", I
can't test it though I see no direct harm in this patch, so unless
someone objects I'll commit it in a day or two.

The patch was a unsubmitted one by the Gentoo people, many thanks to
them for keeping notes about what the patch fixes!
