audit: Handle embedded NUL in TTY input auditing
Data read from a TTY can contain an embedded NUL byte (e.g. after pressing Ctrl-2, or sent to a PTY). After the previous patch, the data would be logged only up to the first NUL. This patch modifies the AUDIT_TTY record to always use the hexadecimal format, which does not terminate at the first NUL byte. The vast majority of recorded TTY input data will contain either ' ' or '\n', so the hexadecimal format would have been used anyway.
