This consolidates internal code to syscallfs, which removes the fs.FS specific path rules, except when adapting one to syscallfs. For example, this allows the underlying filesystem to decide if relative paths are supported or not, as well any EINVAL related concerns. Signed-off-by: Adrian Cole <adrian@tetrate.io>
