Add some functionality via sysctl to syscons.

Browse Source 
hw.syscons.saver.keybonly: used to specify that only input is to
interrupt the screensaver.  This allows one to run a chatty console
app but still have the screen blank out until a key is pressed.
There should probably also be an ioctl for this, we'll do that later.

hw.syscons.saver.blanktime: exports the screensaver timeout via sysctl.
