Memory leak fix for HMAC verification
...
This commit commit fixes a memory leak in the HMAC verification code found with
the test suite running in valgrind mode. Here is the './test-fwknop.pl --diff'
output showing fko_verify_hmac() removed from the flagged functions list:

Make encrypt/decrypt code accept integer key lengths instead of using strlen()
...
Now that encryptions keys and hmac keys may be acquired from /dev/random with
--key-gen (and base64 encoded), they may contain NULL bytes. This emphasizes
the need to not leverage code that assumes C-style strings when making use of
key information.
