Rob Norris ffa0a5af30 Linux 7.0: posix_acl_to_xattr() now allocates memory ...

Kernel devs noted that almost all callers to posix_acl_to_xattr() would
check the ACL value size and allocate a buffer before make the call. To
reduce the repetition, they've changed it to allocate this buffer
internally and return it.

Unfortunately that's not true for us; most of our calls are from
xattr_handler->get() to convert a stored ACL to an xattr, and that call
provides a buffer. For now we have no other option, so this commit
detects the new version and wraps to copy the value back into the
provided buffer and then free it.
