ring-buffer remote: Avoid unexpected symbol warnings (arm, s390)

The now more verbose check found more architecture specific symbol
missing from the whitelist, during randconfig testing on s390
and 32-bit arm:

Unexpected symbols in kernel/trace/simple_ring_buffer.o:
         U __aeabi_unwind_cpp_pr1

Unexpected symbols in kernel/trace/simple_ring_buffer.o:
                 U __s390_indirect_jump_r1
                 U __s390_indirect_jump_r10
                 U __s390_indirect_jump_r14
                 U __s390_indirect_jump_r2
                 U __s390_indirect_jump_r5
                 U __s390_indirect_jump_r7
                 U __s390_indirect_jump_r8
                 U __s390_indirect_jump_r9
make[6]: *** [/home/arnd/arm-soc/kernel/trace/Makefile:160: kernel/trace/simple_ring_buffer.o.checked] Error 1

Add these to the list and keep it roughly sorted into sanitizer
and architecture symbols.
