Misc objtool fixes:

 - Bump up the Clang minimum version requirements
   for livepatch builds, due to Clang assembler
   section handling bugs causing silent
   miscompilations.

 - Strip livepatching symbol artifacts from
   non-livepatch modules.

 - Fix livepatch build warnings when certain
   Clang LTO options are enabled.

 - Fix livepatch build error when
   CONFIG_MEM_ALLOC_PROFILING_DEBUG=y.

 Thanks,

	Ingo
