[PATCH 4/4] gitweb: Remove unused $hash_base parameter from normalize_link_target

[Jakub Narebski <jnareb@gmail.com>]

...since it was decided for normalize_link_target to only mangle
pathname, and do not try to check if target is present in $hash_base
tree, for performance reasons.

This was caugth by Perl::Critic::Policy::Variables::ProhibitReusedNames 
 - Do not reuse a variable name in a lexical scope.

(That was probably me that forgot to remove parameter, but I didn't
search for authorship of this fragment.)
