Fix memory leaks in CTLOG_new_from_base64
Move the call to ct_base64_decode(), which allocates, until after
the check for NULL output parameter.
Also place a cap on the number of padding characters used to decrement
the output length -- any more than two '='s is not permitted in a
well-formed base64 text. Prior to this change, ct_base64_decode() would
return a length of -1 along with allocated storage for an input of
"====".
