Sebastian Bøe d62117e5b8 kconfig: Change how BT affects SYSTEM_WORKQUEUE_PRIORITY
Invalid configurations should be detected during configuration instead
of during compilation whenever possible.

This patch replaces a BUILD_ASSERT on CONFIG_SYSTEM_WORKQUEUE_PRIORITY
with what is intended to be an equivalent Kconfig restriction.
