Improve ACL clearing support (fixing FreeBSD build)

The problem was that f880469173 forgot
that the `#include <sys/xattr.h>` was guarded by an `#ifdef __linux__`.

However, the build failure was only on FreeBSD --- turns out other
platforms have this header too!

The fix therefore uses a new configure check so we properly clear ACLs
on more platforms.
