Subject: [PATCH] LU-4751 hsm: Fix sanity-hsm tests for non-mrsh $PDSH

The workaround for starting backgrounded copytool
monitors via pdsh -Rmrsh is not compatible with non-mrsh
values of $PDSH. This commit adds a branch such that
the workaround is only used when required by the test
cluster environment.
