Stop writing NUL bytes in adbkey.pub.
In N we moved some code from C to C++ without realizing that EVP_EncodedLength
includes space for a terminating NUL and EVP_EncodeBlock writes one. Because
our key reading code copes with the NUL, we never noticed.
Distinguish between the required space returned by EVP_EncodedLength and the
actual number of bytes (not including NUL) used return by EVP_EncodeBlock.
