Subject: [PATCH] Kconfig.debug: drop selecting non-existing HARDLOCKUP_DETECTOR_ARCH

Commit 05a4a9527931 ("kernel/watchdog: split up config options") adds a
new config HARDLOCKUP_DETECTOR, which selects the non-existing config
HARDLOCKUP_DETECTOR_ARCH.

Hence, ./scripts/checkkconfigsymbols.py warns:

HARDLOCKUP_DETECTOR_ARCH
Referencing files: lib/Kconfig.debug

Simply drop selecting the non-existing HARDLOCKUP_DETECTOR_ARCH.

Fixes: 05a4a9527931 ("kernel/watchdog: split up config options")
