perf tui: Make ui__warning modal

By taking the ui__lock so that no other screen updates take place while
waiting for the user.

That was happening when handling an invalid --vmlinux parameter in 'perf
top --tui', with the screen refresh routine repainting the screen and
removing the warning window.
