gitweb: prepare for repositories with packed refs.

When a repository is initialized long time ago with symbolic
HEAD, and "git-pack-refs --prune" is run, HEAD will be a
dangling symlink to refs/heads/ somewhere.

Running -e "$dir/HEAD" to guess if $dir is a git repository does
not give us the right answer anymore in such a case.

Also factor out two places that checked if the repository can be
exported with similar code into a call to a new function,
check_export_ok.
