send-email: Net::SMTP::starttls was introduced in v2.34

We cannot rely on the starttls method being present in Net::SMTP until c274b798e6881a941d941808c6d89966975cb8c8 (Merge branch 'ipv6_ssl' of https://github.com/noxxi/perl-libnet into noxxi-ipv6_ssl, 2014-06-02), which set the module version to 2.34. This version was first shipped as part of perl in v5.21.5~169 (Update libnet to CPAN version 3.01, 2014-10-10). Noticed on an Ubuntu system with perl 5.18.2-2ubuntu1.1, which provides Net::SMTP version 2.31. The error message is Can't locate object method "starttls" via package "Net::SMTP" at /usr/lib/git-core/git-send-email line 1410.
