```
musl: fix alltypes.h and syscall.h not being correct

The previous
[instructions](https://github.com/ziglang/zig/wiki/Updating-libc) for
updating musl libc headers had this (repeated for each architecture):

make DESTDIR=build-all/arm install-headers ARCH=arm

However musl's build system does not properly rebuild alltypes.h and
syscall.h from source, instead using whatever is cached from the
previous build. In the case of the previous time that I updated to musl
1.1.23, this happened to be the aarch64 architecture.

As a workaround, one can remove the obj/ directory to force rebuilding
this file. Now the instructions say this (repeated for each architecture):

rm -rf obj/ && make DESTDIR=build-all/arm install-headers ARCH=arm

This commit updates the resulting headers after this workaround is
applied and the process headers tool is run again.

```
