Marc Alff 257045499f Bug#52312 lost Handler_read_last status variable
Before this fix, the ha_read_last_count status variable was defined and
updated internally, for never exposed as a system variable.

This fix exposes the system variable as "Handler_read_last",
for completness of the Handler_read_* system variables interface.

Adjusted tests results accordingly.
