debug_fuzzer vs '!' and ^Z

Browse Source 
My sysconf allows shell escape, and the fuzzer seems fond of that.
Suppress '!' and also '^Z', although I didn't notice it execute the
latter.  Without this hack, the sequence '!', sub-shell exit, '&'
causes nethack to be killed via SIGTTOU while fiddling with terminal
settings for introff().
