lib/std/fs/test.zig: Some filesystems support 8 EiB files

Btrfs at least supports 16 EiB files (limited in practice to 8EiB by the
Linux VFS code which uses signed 64-bit offsets).  So fix the fs.zig test
case to expect either a FileTooBig or success from truncating a file to
8EiB.  And test that beyond that size the offset is interpreted as a
negative number.

Fixes #24242

```
