Subject: [PATCH] login: Do not dereference proot binds `/bin` and `/etc`

`/bin` and `/etc` are symlinks to `/system/bin` and `/system/etc`, by
default proot will dereference and override them with new contents.

After this change, `/system/bin` and `/system/etc` are kept untouched,
so commands like `/system/bin/ping` can be run directly.
