We don't need flashrom support just for vboot payloads. The current
default (USE_FLASHROM=1) is mostly harmless, especially if libflashrom
is not present (the autodetection in vboot_reference just spits out a
pkg-config error but doesn't actually fail the build), but it's better
to be clear we don't need it.
