Subject: [PATCH] Add musl submodule to .gitmodules

The compiler-builtins subtree has musl as a submodule, but it is not
present in the git root .gitmodules.  This breaks some workflows with
`build.submodules = false` That is, a naive `git submodule update
--init` will error out with:

```
fatal: No url found for submodule path 'library/compiler-builtins/crates/musl-math-sys/musl' in .gitmodules
```
