[clang] [clang][Modules] Raise empty.modulemap expected size to <70KB to fix RISC-V failure (PR #123959)

[Alex Bradbury via cfe-commits]

https://github.com/asb created https://github.com/llvm/llvm-project/pull/123959

I'm not sure why the test is larger for RISC-V than other targets, but we saw this before with #111360.

The file is just over the current 60KB limit:

```
62772 /home/asb/llvm-project/build/stage2/tools/clang/test/Modules/Output/empty.modulemap.tmp/base.pcm
```
