ply-image: Add --print-resolution flag.

This adds a new flag that instructs ply-image to print the
space-separated framebuffer width and height to stdout.

I'm also updating the usage method to list all flags.

BUG=chrome-os-partner:10047
TEST=manual: --print-resolution works; previous behavior still works too
