Fix handling of hex UDP args. (zmap#675)

In the current code it is not possible to pass `--probe-args=hex:..` to the `udp` probe module. The following error message is displayed: ``` udp: unknown UDP probe specification (expected file:/path or text:STRING or hex:01020304 or template:/path or template-fields) ```
