[PATCH 6/8] git-send-email: unconditionally use Net::{SMTP,Domain}

[Ævar Arnfjörð Bjarmason]

The Net::SMTP and Net::Domain were both first released with perl
v5.7.3, since my d48b284183 ("perl: bump the required Perl version to
5.8 from 5.6.[21]", 2010-09-24) we've depended on 5.8, so there's no
reason to conditionally require this anymore.

This conditional loading was initially added in
87840620fd ("send-email: only 'require' instead of 'use' Net::SMTP",
2006-06-01) for Net::SMTP and 134550fe21 ("git-send-email.perl - try
to give real name of the calling host to HELO/EHLO", 2010-03-14) for
Net::Domain, both of which predate the hard dependency on 5.8.
