grub.cfg: drop set pager=1

This was in the very first commit that added a GRUB config to this repo. If set, it causes GRUB to pause output if the screen is full of messages until the user presses a key. That's just incompatible with automation, so nuke it. Any warnings from GRUB should end up in the serial console logs still. One way this can happen is if booting from multipath. GRUB tries each path in turn until it can read from it. For each tried path that's non- optimized, it'll log a message. So if the device has a large enough number of paths, we can trigger the pager functionality and hang boot. Probably fixes: https://issues.redhat.com/browse/OCPBUGS-20123
