kernel: kcsan: kcsan_test: build without structleak plugin

Browse Source 
[ Upstream commit 6fcd4267a8 ]

Building kcsan_test with structleak plugin enabled makes the stack frame
size to grow.

kernel/kcsan/kcsan_test.c:704:1: error: the frame size of 3296 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Turn off the structleak plugin checks for kcsan_test.
