Futher bootloader cleanups

GRUB_OPTS has never been documented as externally available, and is
not used.  Assume it's value to simplify the code.

Move the grub version check separately, as we only support grub2

Remove references to buliding i386 images.  I don't image it works in
any way.

Remove ci.md, which is no longer relevant.

Refactor the test for "building BIOS image on EFI system" consiberably
after these changes.

-CI needs for image building
-===========================
-
-Eventually, if/when TripleO becomes an official OpenStack project, all CI for
-it should be on OpenStack systems. Until then we still need CI.
-
-Jenkins
--------
-
-* Jenkins from jenkins apt repo.
-* IRC notification service, notify-only on #triple on OFTC, port 7000 ssl.
-* Github OAuth plugin, permit all from tripleo organisation, and organisation
-  members as service admins.
-* Grant jenkins builders sudo [may want lxc containers or cloud instances for
-  security isolation]
-* Jobs to build:
- * base ubuntu VM.
-
-        disk-image-create vm base -o base -a i386
-
- * ramdisk deploy image build
-
-        ramdisk-image-create deploy
-
