Make sure refs/rewritten/ is per-worktree

Browse Source 
a9be29c981 (sequencer: make refs generated by the `label` command
worktree-local, 2018-04-25) adds refs/rewritten/ as per-worktree
reference space. Unfortunately (my bad) there are a couple places that
need update to make sure it's really per-worktree.

 - add_per_worktree_entries_to_dir() is updated to make sure ref listing
   look at per-worktree refs/rewritten/ instead of per-repo one [1]

 - common_list[] is updated so that git_path() returns the correct
   location. This includes "rev-parse --git-path".

This mess is created by me. I started trying to fix it with the
introduction of refs/worktree, where all refs will be per-worktree
without special treatments. Unfortunate refs/rewritten came before
refs/worktree so this is all we can do.

This also fixes logs/refs/worktree not being per-worktree.

[1] note that ref listing still works sometimes. For example, if you
    have .git/worktrees/foo/refs/rewritten/bar AND the directory
    .git/worktrees/refs/rewritten, refs/rewritten/bar will show up.
    add_per_worktree_entries_to_dir() is only needed when the directory
    .git/worktrees/refs/rewritten is missing.
