tests: kernel: fix irq_vector_table test for nRF52X platforms

This commit disables Bluetooth and adds a customized vector
table for nRF52X-based platforms in the irq_vector_table kernel
test, in order to prevent UsageFault during system timer
interrupts, and, therefore, let the test execute properly.

This commit fixes #6890.
