generic: filter out CONFIG_FRAME_WARN

generic: filter out CONFIG_FRAME_WARN

CONFIG_FRAME_WARN value is set by config/Config-kernel.in based on the
target type dynamically since commit:
16a2051 ("kernel: Set CONFIG_FRAME_WARN depending on target").

However, CONFIG_FRAME_WARN was not set to get filtered out so it ended up
in multiple target configs during refreshes.
So, lets filter out CONFIG_FRAME_WARN as its set dynamically to prevent it
ending up in more target configs.
