Stefan Weil 89d2d3af51 slirp: Remove some type casts caused by bad declaration of x.tp_buf
x.tp_buf was declared as a uint8_t array, but always used as
a char array (which needed a lot of type casts).

The patch includes these changes:

* Fix declaration of x.tp_buf and remove all type casts.

* Use offsetof() to get the offset of x.tp_buf.
