qemu-common: set icache/dcache line size to 0

From Bionic's sysconf.cpp:

  // We do not have actual implementations for cache queries.
  // It's valid to return 0 as the result is unknown.
  case _SC_LEVEL1_ICACHE_SIZE:      return 0;
  case _SC_LEVEL1_ICACHE_ASSOC:     return 0;
  case _SC_LEVEL1_ICACHE_LINESIZE:  return 0;
  case _SC_LEVEL1_DCACHE_SIZE:      return 0;
  case _SC_LEVEL1_DCACHE_ASSOC:     return 0;
  case _SC_LEVEL1_DCACHE_LINESIZE:  return 0;

So actually it already should be set to 0, but it appears some devices set it
to -1 which triggers assertion error.
