[PATCH 3/4] gitweb: Improve git_print_page_path

[Jakub Narebski <jnareb@gmail.com>]

Add link to "tree root" (root directory) also for not defined name,
for example for "tree" action without defined "file_name" which means
"tree root".

Add " / " at the end of path when $type eq "tree".

Consistency (and code simplification).
