Just a minor cleanup, making it easier to access the command line in the following "Honor quiet in decompressor" patch.
Signed-off-by: Kristian Høgsberg <krh@redhat.com>

Updated this one to be less intrusive; we just re-#define RM_SCREEN_INFO to access the boot_params struct instead of using the hard-coded offset.
