[debug tests] print selected seed for PRNG
Previously the seed was not printed and this created problems with
reproduction of the issues. It's still not an ideal - meaning
interactions between spike/gdb/openocd are inherently non-determistic
(since time is involved), but at least we should get the same sources
for the same seed now.
