Yeah.  I think xxhash-devel is available in most distributions.  XXH32()
could be used directly here and configure.ac needs to be updated to
reflect the package dependency.

As I'm not quite familiar with autoconf/automake, later in v3 I will
still attach the self-implemented xxh32() in erofs-utils.  Maybe later
we could change to use libxxhash directly.
