nonroot tests should call native nodetool

[syuu1228]

On nonroot tests, it defined to call $prefix/share/cassandra/bin/nodetool at:

scylla-cluster-tests/sdcm/cluster.py

Line 2423 in 447dff1

'/usr/bin/nodetool': self.offline_install_dir / 'share/cassandra/bin/nodetool',

Now it broken since we dropped scylla-jmx at scylladb/scylladb@3cd2a61.
And also we will drop scylla-tools from unified installer soon:
scylladb/scylladb#20739

We should call native nodetool which located at $prefix/bin/nodetool.

o.k. so change it to the proper calls, and once all of the artifacts test are passing calling scylla nodetool, we'll be able merge such a change.

@fruch can't we remove scylla-jmx completely from SCT?

From artifact tests it can, but in general we still need to run versions with JMX, since we have releases with it

I've notice it few months ago, and raised it scylladb/scylladb#19185.
I don't think anything change since then, i.e. that scylla nodetool might not work as expect across all the offline tests
