[PATCH] rt: This fixes the boot-up messages related to CONFIG_STACK_TRACER

[John Kacur <jkacur@redhat.com>]

Summary:
- No warning is necessary for CONFIG_STACK_TRACER because it is not enabled by
default anymore.
- The reason it was put back was to fix a problem where there was an
empty REMINDER message about debug options that cause overhead. This is
properly fixed by removing CONFIG_STACK_TRACER from the DEBUG_COUNT

Revert "rt: trivial fix to REMINDER block in init/main.c"

This reverts commit 3e39399ef4a742d994570488994be93ef17d4ef5.

CONFIG_STACK_TRACER really should not be in the reminder block.
By default it is not enabled, and has negligible impact.

rt: Remove CONFIG_STACK_TRACER from DEBUG_COUNT

Remove CONFIG_STACK_TRACER from DEBUG_COUNT so that reminder messages
are printed correctly, and don't leave an empty reminder block for example.
