[PATCH zfsonlinux] d/zfsutils-linux.links: add compat symlinks for zarcstat, zarcsummary

[Stoiko Ivanov]

The patches changing arcstat to zarcstat in our reports[0], brought up
the point that we probably want to re-add the old paths for
arc_summary and arcstat as symlinks for backward compatibility.
I originally oriented the patches on debian-upstream, however new
minor ZFS versions (2.4 vs. 2.3) are only available via backports on
plain debian (and installing from backports is usually a more
conscious step compared to installing the lates updates from our
repositories).

the links orient themselves on the executables shipped in our
zfsutils-linux 2.3.4-pve1.

additionally re-add the conflicts on nordugrid-arc-client, which
still ships (a completely unrelated) arcstat executable.
