unit: Rename x_pdu() macro on SDP test program

Using the "raw_data" name makes sense, given the macro is just casting
input (raw) data. It will also be reused in other tests with raw input
data.

Also fix this minor checkpatch.pl error:

ERROR:COMPLEX_MACRO: Macros with complex values should be enclosed in
parenthesis
+#define raw_data(args...) (const unsigned char[]) { args }
