Fix OTP secret file leak and whitespace removal

In read_secret_file() in the OTP kdcpreauth module, add a cleanup
label and free filename on exit.  Also fix the whitespace stripping
code to correctly find the end offset, and use size_t rather than int
offsets.  The leak was reported by Bean Zhang.
