tests: use Time::HiRes for fractional sleeps in check_ssh

Perl's built-in sleep truncates fractional seconds to zero, so the
existing sleep 0.1 calls did not provide the intended delay.

Import Time::HiRes::sleep to allow netcat time to start before
connecting, reducing the risk of intermittent test failures.
