David Benjamin 367115b056 Fix SSL_CTX_set1_sigalgs fuzzer and make them all more type-safe. 
The size of an int is 4, not 2. To avoid worrying about this, add a GetVector
counterpart to GetString that handles all this. Apply this uniformly to avoid
all the pointer casts. This is less important for vector<uint8_t>, but even
then we'll now notice a 1-byte OOB read since std::string is NUL-terminated.
Also it's shorter.
