worktree: delete .git/worktrees if empty after 'remove'

Browse Source 
For cleanliness, "git worktree prune" deletes the .git/worktrees
directory if it is empty after pruning is complete.

For consistency, make "git worktree remove <path>" likewise delete
.git/worktrees if it is empty after the removal.
