LLVM 22 added i128:128 to the default MIPS64 data layout. rustc rejects
a target spec whose data-layout differs from the one LLVM reports, so
building libstd for mips64 fails:

  error: data-layout for target `mips64-octeon2-linux-gnu`,
  `E-m:e-i8:8:32-i16:16:32-i64:64-n32:64-S128`, differs from LLVM
  target's `mips64-octeon2-linux-gnu` default layout,
  `E-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128`

Add i128:128 to the mips64 and mips64el entries to match, as already
done for the other 64-bit architectures. mips64-n32 is left alone.
