feat(init): unify filesystem walkers for ls/cp APIs (#779)
This unifies low-level filesystem walker code for `ls` and `cp`.

New features:

* `ls` now reports relative filenames
* `ls` now prints symlink destination for symlinks
* `cp` now properly always reports errors from the API
* `cp` now reports all the errors back to the client

Example for `ls`:

```
osctl-linux-amd64 --talosconfig talosconfig ls -l /var
MODE          SIZE(B)   LASTMOD       NAME
drwxr-xr-x    4096      Jun 26 2019   .
Lrwxrwxrwx    4         Jun 25 2019   etc -> /etc
