[3/5] winedump: Dump the raw data when finding an unknown block in an lnk file.

[Francois Gouget]

---

Some lnk files have additional optional data blocks at the end, some of 
which have an unknown format. So at least dump them in binary form so 
one knows they are there, and so one can try to decipher them (e.g. the 
0xa0000003 ones).
