tests: oss-fuzz.sh: Append -fno-sanitize=bounds to CFLAGS

Browse Source 
The new TPM 2 code casts bigNum's to Crypt_Int, which has an array 'd' of
type 'crypt_uword_t[2]' which then leads to the following types of errors
that we haven't found another solution for so far.

Running: /mnt/scratch0/clusterfuzz/bot/inputs/fuzzer-testcases/crash-2675de6341d4e056d04ab49179b8e5b8bd456589
	/src/libtpms/src/tpm2/crypto/openssl/CryptPrime.c:377:20: runtime error: index 23 out of bounds for type 'crypt_uword_t[2]' (aka 'unsigned long[2]')
