Perl 5.8.0 ships with File::Temp 0.13, which does not have the new()

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

This patch v2 cleans up a few code items, corrects a misspelling,
and ensures that the temp file gets unlinked when we exit, now
that we are requesting the filename. Otherwise, the previous
comments stand:
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'.
