Subject: [PATCH] ifaddrs: read_attr closure returns Option, so .ok() the
 read_file Result
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
