mb/*: Fix default fmap with VBOOT_SLOTS_RW_A enabled

Don't select the VBOOT fmap as default if VBOOT is disabled.

Fixes a regression introduced by f8251b98
"mb/emulation/qemu: Add VBOOT support" where the default Kconfig settings
wouldn't allow the qemu boards to run.

Also fix the Supermicro x11-lga1151 series boards.
