Changes in xar:

- Switch to the maintained Apple xar lineage (build 503, versioned

1.8.0.0.503): the mackyle 1.6.1 fork this package tracked has been

dead since 2012, and Debian, Fedora and Gentoo all moved to Apple's

NULL-pointer dereferences in xar_get_path() and xar_unserialize()

when parsing malformed archives:
