weili a70f5ccd7c find: -ls: don't panic on an unmapped owner uid/gid ...

`find <file> -ls` panicked (exit 101) when the file's owning uid (or gid) had
no `/etc/passwd` (`/etc/group`) entry: it resolved the name with
`User::from_uid(...).unwrap().unwrap()`, and the inner unwrap aborts on the
`Ok(None)` that an unmapped id returns. Unmapped owners are routine (extracted
archives, NFS, deleted accounts, container images).

Resolve the uid/gid via `uucore::entries::uid2usr`/`gid2grp`, falling back to
the numeric id when there is no entry, matching GNU find (which prints the
number). These helpers already serialize the non-thread-safe getpwuid/getgrgid
behind a mutex, so reuse them rather than reimplementing the lookup.

Add a -ls integration test that chowns a file to an unmapped id and checks the
numeric fallback; it skips when the process lacks the privilege to do so.
