gitweb: Do not print "log" and "shortlog" redundantly in commit view

Do not print "log" and "shortlog" redundantly in commit
view.  This is passed into the $extra argument of
git_print_page_nav from git_commit, but git_print_page_nav
prints "log" and "shortlog" already with the same head.

Noticed by Junio.
