Fail to start if watch directory contains non-permitted directory

[kdh8219]

Describe the bug

After adding a watch(location) directory, it contains a non-permitted (e.g. root 100) directory, restart the Spacedrive, it gets stuck

Reproduction

> su user

> mkdir foo
> cd foo
> mkdir bar

> sudo chown root bar
> sudo chmod 700 bar

> sudo su
> touch bar/alice
> touch bar/bob

---

1. start spacedrive
2. add location /home/user/foo
3. restart the spacedrive

Expected behavior

Ignore the non-permitted directory and let the program run

Platform and versions

I'm using a released appimage version / v0.1.4 2f01b21

8.14.1
cargo 1.73.0 (9c4383fb5 2023-08-26)
