Title: Add profile option to specify profile target

When my profile target is fixed, adding the same query parameter bothers me.
So I added an `profile` option to choose profile target without query parameter.

### example
```rb
config.middleware.use Rack::Lineprof, profile: 'active_support/core_ext/string'
```
