add Perl requires to git-email

Resolves: rhbz#2020487

In git version 2.33.0, git-send-email.perl has optimized modules
loading[1]. This resulted in perl.req not detecting requires properly,
because it doesn't detect requires that are not at the start of new line.
This commit adds explicit Requires into the spec file.
