Avoid mixing autodie use in different scopes since it's likely
to cause problems like it did in Gcf2. While none of these
fix known problems with test cases, it's likely worthwhile to
avoid it anyways to avoid future surprises.
For Process::IO, we'll add some additional tests in t/io.t
to ensure we don't get unintended exceptions for try_cat.

These only spring up with libgit2-devel installed, but
3/3 seems important for all users of older Perl in
order to avoid future surprises.
