Do not call exit() upon check_bad_algorithms() errors

Browse Source 
Replace all fatal() and fprintf() calls inside check_bad_algorithms()
with zoneverify_print() calls and error handling code.  Enable
check_bad_algorithms() to signal errors to the caller using its return
value.

Modify the call site of check_bad_algorithms() so that its errors are
properly handled.
