Use of a printk that supports floating point changes the stack
requirements causing kernel.common.stack_protection_arm_fpu_sharing to
fail. The test doesn't need this capability so revert to nano
formatting.

Modify the location of the test case file because new
test cases need to be submitted. If the old test
cases are not in a folder, CI will fail and
prompts "the command exited with status 1".
