[libc] wrong header guard on libc/src/__support/big_int.h

[nickdesaulniers]

libc/src/__support/big_int.h has the header guards:

#ifndef LLVM_LIBC_SRC___SUPPORT_UINT_H
#define LLVM_LIBC_SRC___SUPPORT_UINT_H
...
#endif // LLVM_LIBC_SRC___SUPPORT_UINT_H

These 3 should be changed to LLVM_LIBC_SRC___SUPPORT_BIG_INT_H.
