Fix clippy::cmp_owned warning in PathBuf comparison

[Copilot]

Clippy flagged unnecessary heap allocation when comparing PathBuf values in test assertions.

Changes

• Replace path::PathBuf::from("/guest/workingdir/") with path::Path::new("/guest/workingdir/") in test

The get_working_directory() function returns PathBuf, which implements comparison with &Path. Creating a temporary PathBuf for comparison is redundant:

// Before
assert!(
    get_working_directory(&current_directory, &floki_root, &mount)
        == path::PathBuf::from("/guest/workingdir/")
)

// After
assert!(
    get_working_directory(&current_directory, &floki_root, &mount)
        == path::Path::new("/guest/workingdir/")
)

Original prompt

Please fix clippy warnings
