Random #define in utmp.h breaks expat build

[mulle-nat]

There is a #define ACCOUNTING 9 in libc/runtime/utmp. Unfortunately libexpat uses this identifier in xmlparse.c:

typedef unsigned long long XmlBigCount;
typedef struct accounting {
  XmlBigCount countBytesDirect;
  XmlBigCount countBytesIndirect;
  int debugLevel;
  float maximumAmplificationFactor; // >=1.0
  unsigned long long activationThresholdBytes;
} ACCOUNTING;

This define could be deleted I think, since it seems to be used nowhere (searching with github through the cosmopolitan repository).

In a previous version I also stumbled on cosmopolitan doing a #define I which tripped some Objective-C code up. (found it in imag.internal.h). I am not sure, if that's still bothering me, since I #undef it since...
