fix: static file support route_prefix

[solarknight]

Use purely random route for static files if --random-route enabled, otherwise add route_prefix before generated route

Thanks! Any chance you could also make sure this is tested by one of the tests? Otherwise we might get regressions again.

Oh sorry, I'll check the tests ：）

Also check out the CI which failed due to some formatting problem. :)

@solarknight Hey, you still looking into this?

Hey, finally I complete the test for static file route check (really a newbie to rust).
Unfortunately I use push -f by mistake. Do you mind if I make a new PR, or any other suggestions?

[svenstaro]

Could you rebase this so the history becomes tidier?

[svenstaro]

Can you stick this test into serve_request.rs?

[solarknight]

Done, rename the test to keep consistent with existing tests.

@svenstaro All above suggestions should be applied, please review the changes.

Very cool, thanks!
