tcc -run file.c : pass original exit code from file.c again

Browse source 
when there are no other errors then exit tcc with the exit cude
from tcc_run() (messed up in dd2e5f8b06)

Also in tccrun.c, use a more exotic random value to replace zero
with 'exit(0)' in user code (because lonhjmp(jb, c) needs c != 0)
