We need add support for xattr in apk.

We need it for avoid suid root for ‘ping’: #3000.

And will will likely need to migrate our pax marking to xattr: https://wiki.gentoo.org/wiki/Hardened/PaX\_flag\_migration\_from\_PT\_PAX\_to\_XATTR\_PAX

This also means we need to add support for xattr in busybox tar.
