[PATCH] gitweb: Fix thinko in git_tags and git_heads

[Jakub Narebski]

git_get_refs_list always return reference to list (and reference to
hash which we ignore), so $taglist (in git_tags) and $headlist (in
git_heads) are always defined, but @$taglist / @$headlist might be
empty. Replaced incorrect "if (defined @$taglist)" with
"if (@$taglist)" in git_tags and respectively in git_heads.
