scx_rlfifo: print a performance warning banner

Browse Source 
scx_rlfifo is provided as a simple example to show how to use
scx_rustland_core and it's not supposed to be used in a real production
environment.

To prevent performance bug reports print an explicit warning when it's
started to clarify the goal of this scheduler.

**************************************************************************
WARNING: The purpose of scx_rlfifo is to provide a simple scheduler
implementation based on scx_rustland_core, and it is not intended for
use in production environments. If you want to run a scheduler that makes
decisions in user space, it is recommended to use *scx_rustland* instead.
Please do not open GitHub issues in the event of poor performance, or
scheduler eviction due to a runnable task timeout. However, if running this
scheduler results in a system crash or the entire system becoming unresponsive,
please open a GitHub issue.
