tests/kernel/sched/deadline: Disable CONFIG_BT

The BT threads are interfering with the main thread priority selection
and the test fails semi-spuriously on NRF5x boards with "threads ran
too soon" (i.e. not an EDF failure per se, but the fact that the new
threads at K_LOWEST_APPLICATION_PRIO are running instead of the test
thread).  This is a reasonable workaround for testing the
SCHED_DEADLINE ordering behavior, though.

Fixes #9843
