PR26510 UBSAN: tc-z8k.c left shift of negative value

This also fixes the packing of the nibble buffer, which contains
rubbish in the top 4 bits of each element.

PR 26510
* config/tc-z8k.c (buffer): Use unsigned char.
(apply_fix): Use unsigned char* pointers.
(build_bytes): Likewise and mask nibbles when packing.
