getty: Remove 2 second sleep before opening tty

This (apparently very old!) workaround to ensure that DTR stays down long
enough to be detected is now handled by serial drivers themselves. For
console devices (framebuffer, serial console, etc) this was an unnecessary
2 second penalty that we have all been paying since the beginning of time.

Fix another automatic variable that is life both pre- and post the siglongjmp

Fixes the VAX build.
