pg_regress: Disable autoruns for cmd.exe on Windows
This is similar to 9886744a361b, to prevent the execution of other programs due to autorun configurations which could influence the postmaster startup. This was originally applied on HEAD as of 83c75ac7fb69 without a backpatch, but the patch has survived CI and buildfarm cycles. I have checked that cmd /d exists down to Windows XP, which should make this change work correctly in the oldest branches still supported.
