Remove libs/

These are at best a convenience for working on them. They are not used
directly by firmware-open, only as dependencies in other projects.

- coreboot-table: Dependency of apps/firmware-setup
- coreboot-fs: Dependency of apps/firmware-update and libs/intel-spi
- intel-spi: Dependency of apps/firmware-update
- intelfash: Dependency of apps/firmware-update and scripts/modeltool
- uefi: Dependency of a lot of stuff
