[PATCH] Git.pm: require Perl 5.6.1

[Lea Wiemann <lewiemann@gmail.com>]

File::Temp is only in Perl 5.6.1, so Git.pm won't usually work with
older Perl versions; this gives a more descriptive error message
('Perl version too old'), rather than erroring out with a 'File::Temp
not found' message.  (File::Temp is probably not installable on older
Perl version anyway.)
