patch 9.1.1093: tests: output of test ...win32_ctrl_z depends on python version

Problem:  tests: output of test Test_terminal_eof_arg_win32_ctrl_z depends on python
          version.
Solution: Check for the expected output in both, the second last line
          and last line

It seems python 3.13 changed the output a bit and there is no longer a
trailing blank line.  So to keep compatible with python < 3.13, let's
check for the expected output in either the last line and the second
last line.
