There was a copy&paste error in fuzz/isc_lex_getmastertoken.c where we
didn't really test the function we wanted to test. Update the test to
have the input data to always include expected 'tokentype' in the first
byte, `eol` argument in the second byte and the rest of the input is the
data to parse.
In this commit, the simple fuzzing tests for the isc_lex_gettoken() and
isc_lex_getmastertoken() functions have been added.
As part of this commit, the initialization has been moved from fuzz.h
constructor/destructor to LLVMFuzzerInitialize() in each fuzz test. The
main.c of no-fuzzing and AFL modes have been modified to run the
LLVMFuzzerInitialize() at the start of the main() function mimicking
the libfuzzer mode of operation.
