test(ubuntu): work around upstream emulator runner issue

ubuntu-latest == 24 means that command line tools have been updated
a bit, enough to have a "latest" symlink in place on the image, but
not enough to be actually current

This fools the emulator runner though, and it doesn't update the command
line tools because it sees "latest" and thinks that's good enough

So just delete the command line tools completely and let emulator runner
reinstall fresh
