Fix `Dir.statFile` for WASI when linking libc
`statFile` now only uses `os.fstatatWasi` when not linking libc, matching the pattern used throughout other `Dir` functions. This fixes the compilation error: `error: struct 'c.wasi.Stat' has no member named 'fromFilestat'` (which the added test would have failed with)2 files changed, 25 insertions(+), 14 deletions(-)
