[PATCH 6/5] t/v2mirror: check dependencies for legacy test

[Eric Wong <e@80x24.org>]

We still need Email::MIME to test against old revisions.
We'll also depend on the revision just prior to the
manifest.js.gz introduction to avoid loading Danga::Socket,
since it was getting loaded even with `plackup'.

Finally, we'll disable Inline::C usage with old Spawn.pm
since our old code included alloca.h, which is not
portable to FreeBSD.
