cmd: unzip: Use map_sysmem() with buffers in the gzwrite command
The current implementation casts an address to a pointer. Make it more
sandbox-friendly by using map_sysmem().
Convert 'addr' variable to unsigned long, as that is the return type of
hextoul() and address parameter type of map_sysmem().
