Eliminate Scalar::Util usage from private-Error.pm
We used just the blessed() routine so steal it from Scalar/Util.pm. Unfortunately, Scalar::Util is not bundled with older Perl versions. This is a newer much saner blessed() version by Randal L. Schwarz. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
