decompress: change length arguments to long
In order to support decompression of files > 2GiB Linux has changed the prototypes of decompression functions from int uncompress(unsigned char *inbuf, int len, int(*fill)(void*, unsigned int), int(*flush)(void*, unsigned int), unsigned char *output, int *pos, void(*error_fn)(char *x)); to int uncompress(unsigned char *inbuf, long len, long(*fill)(void*, unsigned long), long(*flush)(void*, unsigned long), unsigned char *output, long *pos, void(*error_fn)(char *x)); Do likewise in barebox for easier code sharing with Linux.
