Now that LiteX can convert from VHDL to Verilog using GHDL, and the
required dependencies are installed in the CI environment, start testing
Microwatt.

By default verilator will be built with -j with no arguments, spawning
many processors. This causes large designs to failure in CI (probably
due to exhausting the memory of the build box):
Error: Process completed with exit code 143.
Set the number of jobs to the number of CPUs in the system. This allows
designs such as Microwatt to build in CI.

Also use --opt-level=O0 to reduce compilation time (execution is a bit slower but since we are only
executing the BIOS here, total test time is still reduced).
