unix: align the getdents buffer

getdents64 stores a 64-bit d_ino at the start of every entry, so the entries
are aligned only if the buffer is. Go promises no alignment for a []byte, and
sparc64 faults on the misaligned store rather than fixing it up, returning
EFAULT.

Buffers from make are already 8-aligned, so this is a no-op unless the caller
passes a sub-slice.

Updates golang/go#55000
