pkg_add: Adjust problem detection

[Sunil Nimmagadda]

Hi,

213 is a valid return code from an FTP server for SIZE command and
should not be treated as a problem.

Alternate implementations of FETCH_CMD could provide a slightly
different "Requesting <url>" log lines. Would it be okay to relax
the format a bit and ignore any line starting with "Requesting"
instead.
