vboot: fix STARTS_IN_BOOTBLOCK/_ROMSTAGE logic
Fix up the logic of when to include VBOOT2_WORK symbols on x86, which are only needed when VBOOT_STARTS_IN_BOOTBLOCK is enabled.
Also correct the value of the __PRE_RAM__ macro in the case that VBOOT_STARTS_IN_ROMSTAGE is selected. In this case, DRAM is already up and verstage should not be considered pre-ram.
