archive: Fix the storing of setuid bits, etc

In commit 3dfc910d7774d57c533b067fbe59d6b24dd803cd we changed from
syscall.Chmod() to os.Chmod(), but these take a different form of the
Mode argument. The sycall one takes the raw linux form, wheras
os.Chmod takes the os.FileMode form, and they differ for the higher
bits (setuid, setgid, etc). The raw tar header uses a form which
is compatible with the syscalls, but not the go calls.

We fix this by using hdr.FileInfo() which properly converts the mode
to what go expects.
