Kernel/aarch64: Set kernel_load_base and correctly calculate symbol addr

Browse source 
Setting the kernel_load_base variable caused backtracking to regress, so
to have proper backtracing the calculation of the symbol address in
KSyms.cpp needs to keep into account that the aarch64 kernel is linked
at a high virtual memory address.
