run-make test: using single quotes to not trigger the shell

This test got added in rust-lang#110801.

I'm no expert on Makefiles, but IIUC this command is passed to the shell, which usually tries to execute commands specified in between backticks in double-quoted strings.

Using single quotes should fix this, I think. (Note: Waiting for CI to test this, since I only have a web browser available right now).

Since this is breaking our build bot, even if it is not directly LLVM related: ``@rustbot`` label: +llvm-main
