fix: ignore permission errors during globbing (#6957)
### Description
Fixes https://github.com/vercel/turbo/issues/6863
This brings us closer to the Go behavior where we would ignore [all IO
errors](https://github.com/vercel/turbo/blob/main/cli/internal/doublestar/globwalk.go#L27).
We could do a similar thing by ignoring any error that doesn't have
`ErrorKind::Other`, but that feels like slight overkill to me. I think
ignoring `NotFound` and `PermissionDenied` is probably the sweet spot.
### Testing Instructions
I would love a unit test, but I'm unaware of an easy way to create a
file via Rust that the same process is unable to read. Using a manual
test instead:
Create a directory that you can't read
```
mkdir apps/docs/protected
sudo chown root apps/docs/protected
sudo chmod go-rw apps/docs/protected
```
Verify existing canary fails when running `turbo build`:
```
[0 olszewski@chriss-mbp] /tmp/daemon-bug $ turbo build --output-logs new-only
• Packages in scope: @repo/eslint-config, @repo/typescript-config, @repo/ui, docs, web
• Running build in 5 packages
• Remote caching disabled
ERROR run failed: IO Error: failed to match directory tree: failed to read file at `Some("/private/tmp/daemon-bug/apps/docs/protected")`: Permission denied (os error 13)
```
Build PR and verify that this no longer causes a failure:
```
[1 olszewski@chriss-mbp] /tmp/daemon-bug $ turbo_dev build --output-logs new-only
• Packages in scope: @repo/eslint-config, @repo/typescript-config, @repo/ui, docs, web
• Running build in 5 packages
• Remote caching disabled
