linux-fslc: Fix build issue when compiling LTTng

Fix compile error when building lttng using bitbake by:

Enable kprobes configuration enabled from menuconfig
Run diffconfig
Copy the resulting diff contents into all the linux-fslc defconfig files
Add end of line in defconfig
Built the kernel with no warnings from do_kernel_configcheck task
Add correct defconfig configuration for armv8a
Tested on master branch from 3rd March 2021
