LU-13688 tests: remove duplicate HSM functions

Some HSM test framework functions exist in both test-framework.sh and
sanity-hsm.sh. Some of these are also used in PCC tests, so the
sanity-hsm.sh copy can be removed and some are used only in HSM tests,
so the test-framework.sh copy can be removed. The test-framework.sh
copies were introduced by LU-10092 which seems to have used versions
of the functions before they were updated by LU-11742, so update
kill_copytools() to the latest version.
