torture: Provide EXPERT Kconfig option for arm64 KCSAN torture.sh runs

Browse Source 
The arm64 architecture requires that KCSAN-enabled kernels be built with
the CONFIG_EXPERT=y Kconfig option.  This commit therefore causes the
torture.sh script to provide this option, but only for --kcsan runs on
arm64 systems.
