Add initial RiscV support (#4387)

* Add initial RISCV support

* Add UEFI edge and current kernel configs

* Cleanup and adjust packages

* Those files were in wrong path

* Fix locations

* Ubuntu images built

* Remove Debian support as its too fragile

* Remove Pinta as it doesn't work under riscv

* Limitation is only for building images

* Remove obsolete switch

* Cleanup major arch config files

* Support for Docker building
