Add a shell script (t/t9700-perl-git.sh) that sets up a git repository
and a perl script (t/t9700/test.pl) that runs the actual tests.

Changes since v4:

- Added missing ampersand (thanks Olivier!).
- Use 5.006002 (lowest possible version for Test::More).
- Use File::Temp instead of the external IO::String.

Tested with Perl 5.6, 5.8, 5.10.  Diff against v4 of this patch:
