Deno run with --allow-read and --deny-read flags results in allowed
### Summary `deno run --allow-read --deny-read main.ts` results in allowed, even though 'deny' should be stronger. Same with all global unary permissions given as `--allow-* --deny-*`. ### Details Caused by the fast exit logic in #22894. ### PoC Run the above command expecting no permissions to be passed. ### Impact This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase.
