ci: Use largedisk for loongarch

`dist-loongarch64-linux` and `dist-loongarch64-musl` seem to run out of
disk space when adding the amdgpu LLVM backend. There are changes
underway to free more disk space, but that may take a while, so it was
suggested to switch the affected jobs to a largedisk runner until that
is ready.
