`--ldd` doesn't detect libs with Homebrew version on Fedora

Using Landrun 0.1.15 installed with Homewrew.

Manually adding libs works,
```
$ landrun --add-exec --rox /usr/lib64 /usr/bin/echo "hello"
hello
```

Using `--ldd` fails.
```
$ landrun --add-exec --ldd /usr/bin/echo "hello"
[landrun:error] 2026/03/02 06:37:49 permission denied
```
