flashrom: Add some helpful hints about missing Linux kernel configs

I was watching a colleague run into trouble trying to use flashrom
on a minimally-configured Linux (used as a coreboot payload) that
was missing some CONFIGs that flashrom needs. Of course, these are
pretty easy to find for the experienced user, but might as well
give the hint about which CONFIG is missing right in the error
message.
