Fix unstowing with --compat --dotfiles

Unstowing with `--dotfiles` didn't work with `--compat`, because when
traversing the target tree rather than the package tree, there was no
mechanism for mapping a `.foo` file or directory back to its original
`dot-foo` and determine whether it should be unstowed.

So add a reverse `unadjust_dotfile()` mapping mechanism to support
this.
