Teach ftpErrString to format UNIX errnos, since at least ftpLogin()
can return UNIX errnos.  When UNIX errnos catch up with FTP status
codes (e.g. at 100) a new way will have to be found to tell which
is which.

This allows fetch to print errors like
fetch: ftp.fu-berlin.de: No route to host
instead of
fetch: ftp.fu-berlin.de: Unknown error
