lib/decompress_bunzip2.c: fix checkstack warning

Fix checkstack error:

lib/decompress_bunzip2.c: In function `get_next_block':
lib/decompress_bunzip2.c:511: warning: the frame size of 1932 bytes is larger than 1024 bytes

byteCount, symToByte, and mtfSymbol cannot be declared static or allocated
dynamically so place them in the bunzip_data struct.
