scripts/build-fpga-{bitstream,rom}: refuse to run outside the chroot
These are no longer expected to work outside the chroot. Add an error
message to remind people in case they try running outside the chroot.
Otherwise they will get a potentially confusing error about some missing
command or Python package.
