ifaddrs: read_attr closure returns Option, so .ok() the read_file Result

Browse Source 
The read_attr closure is typed -> Option<Vec<u8>> and its callers use
`if let Some(...)`, but it returned read_file(...) directly, which is
Result<Vec<u8>, ()> — E0308. Map it with .ok() (Ok->Some, Err(())->None).
Fixes the relibc compile error that failed the prefix rebuild.
