LU-17968 tests: sanity-hsm 35 slow VM timeout fix

Test 35 in sanity-hsm.sh has been failing intermittently since
2021-07-25, with a rate around 1/1300 runs. This is likely
caused by occasional slow VM behaviour so the timeout has been
increased from 1s to 2s to hopefully avoid future occurences
while maintaining test functionality.
