Add special-case signature for test_done in riscv_csr_test

Browse source 
This test is generated differently to all the others, as it exclusively uses a
python script.
The easiest way to make this work with the new test_done signature address is to
detect it as a special case and pass it the new address. The handshaking is only
used for ending the test, so the original address does not matter.
