The yara_scan API parses the file generated by the daemon counterpart
function and returns the list of yara_detection structs to the user.
It writes the daemon's command output on a temporary file and parses it,
deserialising the XDR formatted yara_detection structs.
It returns to the caller the list of yara_detection structs generated by
the internal_yara_scan command.
