[PATCH] Git.pm: Use File::Temp->tempfile instead of ->new

[Marcus Griep <marcus@griep.us>]

Perl 5.8.0 ships with File::Temp 0.13, which does not have the new()
interface introduced in 0.14, as pointed out by Tom G. Christensen.

This modifies Git.pm to use the more established tempfile() interface
and updates 'git svn' to match.

Signed-off-by: Marcus Griep <marcus@griep.us>

 Per the earlier patch versions by Abhijit Menon-Sen and Tom G. Christensen.
 Both of you may want to run a test and add your 'Tested-by' to the thread
 if everything works out before Eric Wong adds his 'Acked-by'.
